TLC271CP

Texas Instruments · Operational Amplifier · PDIP-8

TLC271CP from Texas Instruments, in a PDIP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OFFSET N1 passive Offset null terminal N1, used with OFFSET N2 to null the input offset voltage; the excerpt gives no further limits for this pin.
2 IN - input Inverting input; the common-mode input voltage range extends below the negative rail for C-suffix and I-suffix types.
3 IN + input Noninverting input; the common-mode input voltage range extends below the negative rail for C-suffix and I-suffix types.
4 GND power_in Negative supply rail (ground) for single-supply operation; the output voltage range includes this negative rail.
5 BIAS SELECT input Selects high, medium, or low bias mode to trade power dissipation against ac performance (typical PD 3.4, 0.5, and 0.05 mW at VDD = 5 V, TA = 25°C).
6 VDD power_in Positive supply; the C-suffix (0°C to 70°C) devices operate from 3 V to 16 V supply.
7 OUT output Amplifier output; the output voltage range includes the negative rail.
8 OFFSET N2 passive Offset null terminal N2, used with OFFSET N1 to null the input offset voltage; the excerpt gives no further limits for this pin.
