The AD8519 and AD8529 are rail-to-rail output bipolar amplifiers with a unity gain bandwidth of 8 MHz and a typical voltage offset of less than 1 mV. The AD8519 brings precision and bandwidth to the SOT-23 package. The low supply current makes the AD8519/AD8529 ideal for battery powered applications. The rail-to-rail output swing of the AD8519/AD8529 is larger than standard video op amps, making them useful in applications that require greater dynamic range than standard video op amps. The +2.7 V/s slew rate makes the AD8529/AD8549 a good match for driving ASIC inputs such as voice codecs. The small SOT-23 package makes it possible to place the AD8519 next to sensors, reducing external noise pickup. The AD8519/AD8529 is specified over the extended industrial (-40C to +125C) temperature range. The AD8519 is available in 5-lead SOT-23-5 and SO-8 surface mount packages. The AD8529 is available in 8-lead SOIC and SOIC packages.

APPLICATIONS INFORMATION Maximum Power Dissipation
Figure 20. Precision Full-Wave Rectifier
The maximum power that can be safely dissipated by the AD8519/ AD8529 is limited by the associated rise in junction temperature. The maximum safe junction temperature is +150C for these plastic packages. If this maximum is momentarily exceeded, proper circuit operation will be restored as soon as the die temperature is reduced. Operating the product in the "overheated" condition for an extended period can result in permanent damage to the device.
Precision Full-Wave Rectifier
Slew Rate is probably the most underestimated parameter when designing a precision rectifier. Yet without a good slew rate large glitches will be generated during the period when both diodes are off. Let's examine the operation of the basic circuit before considering slew rate further, U1 is set up to have two states of operation. D1 and D2 diodes switch the output between the two states. State one is as an inverter with a gain of 1 and state two is a simple unity gain buffer where the output is equal to the value of the virtual ground. The virtual ground is the potential present at the noninverting node of the U1. State one is active when VIN is larger than the virtual ground. D2 is on in this condition. If VIN drops below virtual ground, D2 turns off and D1 turns on. This causes the output of U1 to simply buffer the virtual ground and this configuration is state two. So, the function of U1, which results from these two states of operation, is a half-wave inverter. The U2 function takes the inverted half-wave at a gain of two and sums it into the original VIN wave, which outputs a rectified full-wave. VOUT = VIN - 2 VIN
-1
This type of rectifier can be very precise if the following electrical parameters are adhered to: First, all passive components should be of tight tolerance, 1% resistors and 5% capacitors. Second, if the application circuit requires high impedance (i.e., direct sensor interface), then an FET amplifier is probably a better choice than the AD8519. Third, an amp such as the AD8519, which has a great slew rate specification, will yield the best result, because the circuit involves switching. Switching glitches are caused when D1 and D2 are both momentarily off. This condition occurs every time the input signal is equal to the virtual ground potential. When this condition occurs the U1 stage is taken out of the VOUT equation and VOUT is equal to VIN R5 (R4 R1+R2+R3). Please note: node A should be VIN inverted or virtual ground, but in this condition node A is a simply tracking VIN. Given a sine wave input centered around virtual ground glitches are generated at the sharp negative peaks of the rectified sine wave. If the glitches are hard to notice on an oscilloscope, then raise the frequency of the sine wave till they become apparent. The size of the glitches are proportional to the input frequency, the diode turn-on potential (+0.2 V or +0.65 V) and the slew rate of the op amp. R6 and R7 are both necessary to limit the amount of bias current related voltage offset. Unfortunately, there is no "perfect" value for R6 because the impedance at the inverting node is altered as D1 and D2 switch. Therefore, there will also be some unresolved bias current related offset. To minimize this offset, use lower value resistors or choose an FET amplifier if the optimized offset is still intolerable. The AD8519 offers a unique combination of speed vs. power ratio at +2.7 V single supply, small size (SOT-23), and low noise that make it an ideal choice for most high volume and high precision rectifier circuits.
10 Microphone Preamp, Meets PC99 Specifications
<0
This circuit, while lacking a unique topology, is anything but featureless when an AD8519 is used as the op amp. This preamp gives 20 dB gain over a frequency range of 20 Hz to 20 kHz and is fully PC99 compliant in all parameters including THD+N, dynamic range, frequency range, amplitude range, crosstalk, etc. Not only does this preamp comply with the PC99 spec it far surpasses it. In fact, this preamp has a VOUT noise of around 100 dB, which is suitable for most professional 20-bit audio systems. Referred to input noise is 120 dB. At 120 dB THD+N in unity gain the AD8519 is suitable for all 24-bit professional audio systems available today. In other words, the AD8519 will not be the limiting performance factor in your audio system despite its small size and low cost. REV. A -9-
AD8519/AD8529
Slew-rate-related distortion would not be present at the lower voltages because the AD8519 is so fast at 2.1 V/s. A general rule of thumb for determining the necessary slew rate for an audio system is: Take the maximum output voltage range of the device given the design's power rails and divide by two. In our example in Figure 21, the power rails are +2.7 V and the output is rail-to-rail: enter those numbers into the equation 2.7/2 is +1.35 V, and our minimum ideal slew rate is 1.35 V/s. While this data sheet gives only one audio example, many audio circuits are enhanced with the use of the AD8519. Here are just a few examples, Active audio filters like bass, treble and equalizers, PWM filters at the output of audio DACs, Buffers and Summers for mixing stations, and Gain stages for volume control.

Figure 22 is a schematic of a two-element varying bridge. This configuration is commonly found in pressure and flow transducers. With two-elements varying the signal will be 2 as compared to a single-element varying bridge. The advantages of this type of bridge are gain setting range, no signal input equals 0 V out, and single supply application. Negative characteristics are nonlinear operation and required R matching. Given these sets of conditions, requirements and characteristics, the AD8519 can be successfully used in this configuration because of its rail-torail output and low offset. Perhaps the greatest benefits of the AD8519, when used in the bridge configuration, are the advantages it can bring when placed in a remote bridge sensor. For example: the tiny SOT-23 package will reduce the overall sensor package, low power allows for remote powering via batteries or solar cells, high output current drive to drive a long cable, and +2.7 V operation for two cell operation.
