Product details

1 pA input bias, 900 µV offset — sensor front-end fit

The TS274AIPT: Input bias current is 1 pA typical, which keeps the voltage error across a 10 kΩ source resistor below 10 nV — negligible for most precision loops. The 900 µV maximum input offset is moderate; for a gain of 100 the output offset sits at 90 mV, acceptable for many industrial-level thresholds but worth budgeting in a high-gain chain. Each of the four amplifiers can source or sink 45 mA, enough to drive a moderate load or a 2 kΩ feedback network without significant swing loss.

RoHS3 compliant — no restricted substances above the threshold, so it passes EU regulatory checks without an exemption review.

Frequently asked questions

Will the TS274AIPT drop into a board designed for the TS27M2BIDT?

Not without a board spin. The TS274AIPT is a quad (4-circuit) amplifier in a 14-TSSOP package, while the TS27M2BIDT is a dual (2-circuit) amplifier in a different pinout. The functions are similar — both are CMOS op-amps with 1 pA input bias — but the pin assignments and package size differ.
