Product details

It delivers a gain bandwidth product of 2.2 MHz and a slew rate of 3.6V/µs, making it a solid choice for signal conditioning, active filters, and sensor amplification in equipment that stays indoors — the 0°C to 70°C commercial temperature range means it's not rated for an engine bay or a freezer line. Supply spans 3V to 16V, so it runs off a single 5V rail or dual ±5V supplies without a regulator change. Input bias current is 0.6 pA, which keeps offset errors negligible when buffering high-impedance sources like photodiodes or pH probes.

Supply current and output drive

Total quiescent supply current is 2.7 mA for all four amplifiers combined. Each output can source or sink 30 mA.

Frequently asked questions

Is TLC274CD rail-to-rail output?

No, the TLC274CD is a general-purpose amplifier with a standard output stage, not rail-to-rail. Output swing depends on load current and supply voltage — expect about 1V to 1.5V from each rail under moderate load.

What is the difference between TLC274CD and LM324?

Both are quad general-purpose op-amps in similar pinouts, but the TLC274CD has a much lower input bias current (0.6 pA vs typically 20 nA for LM324), higher GBW (2.2 MHz vs 1 MHz), and lower supply current per channel. The LM324 runs on a wider supply range (3V to 32V) and is available in industrial temperature grades. For precision low-bias applications, the TLC274CD is the better fit.

What is the equivalent or replacement for TLC274CD?

A functional alternative with similar quad configuration and higher bandwidth is the OPA4374AIPWT (6.5 MHz GBW, 5 V/µs slew, rail-to-rail output, -40°C to 125°C). It is not pin-compatible — verify the pinout and compensation before substituting. No direct second-source is listed.
