TC1034/TC1035
Linear Building Block - Single Operational Amplifiers in SOT Packages
Features
* * * * Tiny SOT-23A Package Optimized for Single Supply Operation Ultra Low Input Bias Current: Less than 100pA Low Quiescent Current: 6A (Typ.) Shutdown Mode: 0.05A (Typ.) (TC1035) * Shutdown Mode (TC1035) * Rail-to-Rail Inputs and Outputs
General Description
The TC1034/TC1035 are single CMOS operational amplifiers for low power applications. They have a typical operating supply current of 6A, which is constant over the supply voltage range of 1.8V to 5.5V. The Op Amp has a rail-to-rail input and output which allows operation at low supply voltages with large input and output signal swings. An active low shutdown input, SHDN, is available on the TC1035 and disables the op amp, placing its output in a high-impedance state. The TC1035 draws less than 0.1A when the shutdown mode is active. Packaged in a 5-Pin SOT-23A (TC1034) or 6-Pin SOT23A (TC1035), these single operational amplifiers are ideal for applications requiring high integration, small size and low power. Temperature Range -40C to +85C -40C to +85C

3.0 DETAILED DESCRIPTION 4.0 TYPICAL APPLICATIONS
The TC1034/TC1035 is one of a series of very low power, linear building block products targeted at low voltage, single supply applications. The TC1034/ TC1035 minimum operating voltage is 1.8V and maximum supply current is only 8A. The TC1034 is a single op amp in a 5-Pin SOT-23A package, and the TC1035 is a single op amp with shutdown input in a 6-Pin SOT-23A package. Microchip's op amps are internally compensated to be unity gain stable and have a typical gain bandwidth product of 90kHz with typical slew rates of 35V/msec. The amplifier's input range extends beyond both supplies by 200mV and the outputs will swing to within several millivolts of the supplies depending on the load current being driven. Input offset voltage is 500V max at 25C with an input bias current of less than 100pA. This makes these devices extremely suitable for precision, low power applications. The TC1034/TC1035 lends itself to a wide variety of applications, particularly in battery powered systems. It typically finds applications in power management, processor supervisory and interface circuitry.
4.1
Voice Band Receive Filter
The majority of spectral energy for human voices is found to be in a 2.7kHz frequency band from 300Hz to 3kHz. To properly recover a voice signal in applications such as radios, cellular phones and voice pagers, a low power bandpass filter that is matched to the human voice spectrum can be implemented using Microchip's CMOS op amps. Figure 4-1 shows a unity gain multipole Butterworth filter with ripple less than 0.15dB in the human voice band. The lower 3dB cut-off frequency is 70Hz (single order response), while the upper cut-off frequency is 3.5kHz (fourth order response).
4.2
Supervisory Audio Tone (SAT) Filter for Cellular
Supervisory Audio Tones (SAT) provide a reliable transmission path between cellular subscriber units and base stations. The SAT tone functions much like the current/voltage used in land line telephone systems to indicate that a phone is off the hook. The SAT tone may be one of three frequencies: 5970, 6000 or 6030Hz. A loss of SAT implies that channel conditions are impaired and if SAT is interrupted for more than 5 seconds a cellular call is terminated. Figure 4-2 shows a high Q (30) second order SAT detection bandpass filter using Microchip's CMOS op amp architecture. This circuit nulls all frequencies except the three SAT tones of interest.
