That current budget includes all four channels, so a multi-stage filter or a quad-sensor interface can run continuously without draining a coin cell. The trade-off is speed: the 110 kHz GBW and 0.05 V/µs slew rate limit you to signals below roughly 10 kHz for decent gain accuracy. For a temperature monitor or a pressure-sensor bridge that updates at a few hertz, this is exactly the right part. ## Input bias current: 0.7 pA The CMOS input stage delivers a typical input bias current of 0.7 pA. That matters when your source impedance is high — think pH probes, piezoelectric sensors, or high-megohm resistor dividers. The voltage offset is 1.1 mV typical, which is reasonable for this class; if you need sub-millivolt precision, you'd step to a chopper-stabilized part, but for general-purpose low-frequency work the offset is fine. The 14-SOIC package is hand-solderable with a fine tip and some flux — no hot-air gun required if you're careful.","metaTitle":"TLC27L4ACDR CMOS Quad Op-Amp, 110 kHz GBW, 57 µA Supply","metaDescription":"Texas Instruments TLC27L4ACDR quad CMOS op-amp. 110 kHz GBW, 0.05 V/µs slew rate, 57 µA supply for four channels.
