Quad precision amplifier for multi-channel signal chains
The Texas Instruments OPA4205ADR is a quad general-purpose operational amplifier from the e-trim™ series, packing four rail-to-rail output stages into a 14-SOIC package. It delivers a 3.6 MHz gain-bandwidth product and a 4V/µs slew rate, with a maximum input offset voltage of 4 µV and input bias current of 100 pA. The part operates from a single 4.5 V to 36 V supply or split supplies, drawing just 220 µA total quiescent current across all four amplifiers. This combination suits multi-channel industrial signal conditioning, sensor front-ends, and active filter stages where board space is tight and per-channel power budget matters.
Lifecycle and sourcing reality
The OPA4205ADR carries an active lifecycle status and is ROHS3 compliant. The e-trim™ series designation indicates on-chip trim calibration during manufacturing, which holds the offset voltage tight without external adjustment.
