Quad op amp at 570 µA total supply
The TLC27M4AIDR is a quad general-purpose op amp from Texas Instruments' LinCMOS™ series, packing four amplifiers in a single 14-SOIC package. Total supply draw is 570 µA across all four channels — 143 µA per amplifier — which keeps the thermal budget low in dense mixed-signal boards.
525 kHz GBW with 0.7 pA input bias
Gain-bandwidth product sits at 525 kHz with a 0.62 V/µs slew rate — adequate for audio-band filtering, sensor conditioning, and slow control loops where the signal bandwidth stays under 50 kHz. The 0.7 pA typical input bias current means the TLC27M4AIDR can interface directly with high-impedance sources like pH probes or photodiode front-ends without a separate buffer stage. Input offset voltage is 900 µV typical, and each output can source or sink 30 mA. The 4 V to 16 V supply span covers single 5 V rails up to ±8 V split supplies, so the same part works across 3.3 V sensor rails and 12 V industrial analog front-ends.
Industrial temperature grade, active production
Rated for -40°C to 85°C operation, the TLC27M4AIDR fits factory-floor and outdoor enclosure environments where the ambient stays within the industrial band. The 14-SOIC (0.154", 3.90 mm width) footprint is a standard JEDEC outline shared across many TI quad op amps — the PCB land pattern is interchangeable with other 14-pin SOIC parts in the same function class, simplifying second-source qualification.
