GS8552-SR

GS8552-SR is the SOP-8 tape-and-reel ordering code for the Gainsil GS8552 dual zero-drift operational amplifier, listed word-for-word in the package and ordering information of the Gainsil GS8551/GS8552/GS8554 datasheet (V2) at 4,000 pieces per reel. Gainsil publishes no lifecycle grading system; the code is current in that datasheet. Its input offset voltage is 1 µV typical and 30 µV maximum, with drift of 0.03 µV/°C typical, input bias current of 20 pA typical, CMRR of 110 dB and PSRR of 115 dB, quiescent current of 180 µA typical per amplifier, gain-bandwidth of 1.8 MHz typical, slew rate of 0.95 V/µs typical and input noise of 38 nV/√Hz typical at 1 kHz, from a 1.8 V to 5.5 V supply over -45 °C to +125 °C. The selection point is a dual zero-drift amplifier in the commodity SOP-8 body for current-sense, bridge and weighing front ends that cannot afford offset drift over temperature. Selection advice: zero-drift (chopper) amplifiers trade pulsed input current and clock feedthrough for their offset performance, so check the datasheet input-current behaviour before pairing one with a very high source impedance. Parameters verified against the Gainsil GS8551/GS8552/GS8554 datasheet V2 (ordering information and electrical characteristics).
