What this quad op-amp is and where it fits
The Texas Instruments TLC274CD is a quad general-purpose operational amplifier in a 14-SOIC surface-mount package. 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.
