Quad CMOS op-amp for multi-channel signal conditioning
The CMOS input stage keeps input bias current at 0.02 pA typical, preserving signal integrity when interfacing with high-impedance sources like photodiodes or pH probes.
Supply current and power budgeting across four channels
Total supply current is 1.3 mA for all four amplifiers combined, which works out to roughly 325 µA per channel. In a battery-powered multichannel data logger or portable instrument, that current draw per amplifier is low enough to keep the power budget manageable without resorting to micropower op-amps that trade off bandwidth. Each channel can source or sink 8 mA of output current, adequate for driving moderate loads like the input of an ADC or a following filter stage.
Input offset voltage and DC accuracy considerations
The input offset voltage is specified at 500 µV. For precision DC applications like thermocouple amplification or bridge sensor readouts, that offset may require a calibration step or a downstream offset-nulling stage. The CMOS input stage's 0.02 pA bias current, however, means negligible voltage error from source impedance — a 10 MΩ source adds only 0.2 µV of offset error, which is orders of magnitude below the amplifier's own offset.
Temperature range and deployment environment
That makes it a fit for outdoor telecom enclosures, factory-floor sensor modules, automotive cabin electronics, and HVAC controllers. The 14-TSSOP package is surface-mount, so it goes through standard reflow profiles; no special handling beyond MSL precautions.
