SETTLING TIME (tS) vs CLOSED LOOP GAIN FIGURE 40. ZOUT vs FREQUENCY Applications Information Functional Description The ISL28110 and ISL28210 are single and dual 12.5 MHz precision JFET input op amps. These devices are fabricated in the PR40 Advanced Silicon-on-Insulator (SOI) bipolar-JFET process to ensure latch-free operation. The precision JFET input stage provides low input offset voltage (300V max @ +25C), low input voltage noise (6nV/Hz), and input current noise that is very low with virtually no 1/f component. A high current complementary NPN/PNP emitter-follower output stage provides high slew rate and maintains excellent THD+N performance into heavy loads (0.0003% @ 10VP-P @ 1kHz into 600). voltage range of 33V. Internal ESD protection diodes clamp the non-inverting and inverting inputs to one diode drop above and below the V+ and V- the power supply rails ("Pin Descriptions" on page 2, CIRCUIT 1). Input ESD Diode Protection The JFET gate is a reverse-biased diode with >33V reverse breakdown voltage which enables the device to function reliably in large signal pulse applications without the need for anti-parallel clamp diodes required on MOSFET and most bipolar input stage op amps. No special input signal restrictions are needed for power supply operation up to 15V, and input signal distortion caused by nonlinear clamps under high slew rate conditions are avoided. For power supply operation greater than 16V (>32V), the internal ESD clamp diodes alone cannot clamp the maximum input differential signal to the power supply rails without the risk of exceeding the 33V breakdown of the JFET gate. Under these conditions, differential input voltage limiting is necessary to prevent damage to the JFET input stage. Operating Voltage Range The devices are designed to operate over the 9V (4.5V) to 40V (20V) range and are fully characterized at 10V (5V) and 30V (15V). The JFET input stage maintains high impedance over a maximum input differential 14 FN6639.1 December 8, 2010 ISL28110, ISL28210 In applications where one or both amplifier input terminals are at risk of exposure to voltages beyond the supply rails, current limiting resistors may be needed at each input terminal (see Figure 41 RIN+, RIN-) to limit current through the power supply ESD diodes to 20mA. V+ RINRIN + Output Drive Capability The complementary bipolar emitter follower output stage features low output impedance (Figure 40) and is capable of substantial current drive over the full temperature range (Figures 27, 28) while driving the output voltage close to the supply rails. The output current is internally limited to approximately 50mA at +25C. The amplifiers can withstand a short circuit to either rail as long as the power dissipation limits are not exceeded. This applies to only 1 amplifier at a time for the dual op amp. Continuous operation under these conditions may degrade long term reliability. VINVIN+ RL V- Output Phase Reversal Output phase reversal is a change of polarity in the amplifier transfer function when the input voltage exceeds the supply voltage. The ISL28110 and ISL28210 are immune to output phase reversal, out to 0.5V beyond the rail (VABS MAX) limit. Beyond these limits, the device is still immune to reversal to 1V beyond the rails but damage to the internal ESD protection diodes can result unless these input currents are limited. FIGURE 41. INPUT ESD DIODE CURRENT LIMITING JFET Input Stage Performance The ISL28110, ISL28210 JFET input stage has the linear gain characteristics of the MOSFET but can operate at high frequency with much lower noise. The reversedbiased gate PN gate junction has significantly lower gate capacitance than the MOSFET, enabling input slew rates that rival op amps using bipolar input stages. The added advantage for high impedance, precision amplifiers is the lack of a significant 1/f component of current noise (Figures 13, 14) as there is virtually no gate current. The input stage JFETs are bootstrapped to maintain a constant JFET drain to source voltage which keeps the JFET gate currents and input stage frequency response nearly constant over the common mode input range of the device. These enhancements provide excellent CMRR, AC performance and very low input distortion over a wide temperature range. The common mode input performance for offset voltage and bias current is shown in Figure 42. Note that the input bias current remains low even after the maximum input stage common mode voltage is exceeded (as indicated by the abrupt change in input offset voltage). NORMALIZED INPUT BIAS CURRENT (pA) Maximizing Dynamic Signal Range The amplifiers maximum undistorted output swing is a figure of merit for precision, low distortion applications. Audio amplifiers are a good example of amplifiers that require low noise and low signal distortion over a wide output dynamic range. When these applications operate from batteries, raising the amplifier supply voltage to overcome poor output voltage swing has the penalty of increased power consumption and shorter battery life. Amplifiers whose input and output stages can swing closest to the power supply rails while providing low noise and undistorted performance, will provide maximum useful dynamic signal range and longer battery life. Rail-to-rail input and output (RRIO) amplifiers have the highest dynamic signal range but their added complexity degrades input noise and amplifier distortion. Many contain two input pairs, one pair operating to each supply rail. The trade-offs for these are increased input noise and distortion caused by non-linear input bias current and capacitance when amplifying high impedance sources. Their rail-to-rail output stages swing to within a few millivolts of the rail, but output impedances are high so that their output swing decreases and distortion increases rapidly with increasing load current. At heavy load currents the maximum output voltage swing of RRO op amps can be lower than a good emitter follower output stage. The ISL28110 and ISL28210 low noise input stage and high performance output stage are optimized for low THD+N into moderate loads over the full -40C to +125C temperature range. Figures 19 and 20 show the 1kHz THD+N unity gain performance vs output voltage swing at load resistances of 2k and 600. Figure 43 shows the unity-gain THD+N performance driving 600 from 5V supplies. 10 8 6 4 2 0 -2 -4 -6 -8 -10 -15 -10 -5 0 VCM (V) 5 INPUT BIAS (IB) INPUT OFFSET VOLTAGE (VOS) VS = 15V T = +25C 500 400 200 100 0 -100 -200 -300 -400 -500 15 NORMALIZED VOS (uV) 300 10 FIGURE 42.
