The total supply current of 57 µA across all four amplifiers makes it a strong candidate for battery-powered instrumentation, portable medical devices, or loop-powered 4-20 mA transmitters where every microamp counts. The input bias current of 0.7 pA allows direct connection to high-impedance sources like photodiodes or pH electrodes without an external buffer, preserving signal integrity in low-level measurements. The TLC27L4ACD operates from a single supply spanning 3 V to 16 V, covering common 3.3 V, 5 V, and 12 V rails without a separate negative supply. The 1.1 mV typical input offset voltage is adequate for general-purpose sensing; if tighter offset is needed, the precision-grade TLC27L4B variant is worth evaluating. For extended temperature requirements, the TLC27L4AID (industrial grade, -40°C to 125°C) is the same die in the same package.","metaTitle":"TLC27L4ACD Texas Instruments LinCMOS Quad Op-Amp, 110 kHz","metaDescription":"Texas Instruments TLC27L4ACD CMOS quad op-amp, 110 kHz GBW, 0.05 V/µs slew rate, 57 µA supply, 0.7 pA bias.

The OPA4374 draws 600 µA per channel versus 14.25 µA per channel for the TLC27L4ACD.
