TLC272

Texas Instruments · Operational Amplifier · SOIC-8

The TLC272 is a dual operational amplifier built on TI's LinCMOS process, giving high input impedance, low input bias current, and low power draw. It works from a single 3 V to 16 V supply and suits high-impedance sensor buffering, active filters, and general single-supply signal conditioning.

Pinout

Pin Name Type Function
1 1OUT output Output of amplifier 1. Drives up to ±30 mA; high-level output typ 4.95 V at VDD = 5 V, RL = 10 kΩ; low-level output includes negative rail (0 V).
2 1IN- input Inverting input of amplifier 1. High input impedance (>10^12 Ω typ), input bias current typ 10 pA at 25°C. Common-mode input voltage range extends to −0.1 V (below negative rail).
3 1IN+ input Non-inverting input of amplifier 1. High input impedance (>10^12 Ω typ), input bias current typ 10 pA at 25°C. Common-mode input voltage range extends to −0.1 V (below negative rail).
4 GND power_in Negative supply / ground reference. Total current out of GND ≤ 45 mA (absolute max). Serves as the negative rail for single-supply operation.
5 2IN+ input Non-inverting input of amplifier 2. High input impedance (>10^12 Ω typ), input bias current typ 10 pA at 25°C. Common-mode input voltage range extends to −0.1 V (below negative rail).
6 2IN- input Inverting input of amplifier 2. High input impedance (>10^12 Ω typ), input bias current typ 10 pA at 25°C. Common-mode input voltage range extends to −0.1 V (below negative rail).
7 2OUT output Output of amplifier 2. Drives up to ±30 mA; high-level output typ 4.95 V at VDD = 5 V, RL = 10 kΩ; low-level output includes negative rail (0 V).
8 VDD power_in Positive supply pin. Operating range 3 V to 16 V (C-suffix) or 4 V to 16 V (I-suffix); absolute max 18 V. Supply current typ 1.12 mA (both amplifiers, no load) at VDD = 5 V.
