OPA2277UA/2K5

OPA2277UA/2K5 is the 2,500-piece tape-and-reel SOIC-8 ordering code for the Texas Instruments OPA2277 dual precision operational amplifier, listed by TI as ACTIVE on the buying page and in the datasheet ordering appendix (SBOS079) for this /2K5 variant itself. It holds input offset to 10 µV typical and ±20 µV maximum with drift of ±0.1 µV/°C typical, open-loop gain of 134 dB typical, common-mode rejection of 140 dB typical, power-supply rejection of 130 dB typical, input bias current of 500 pA typical and 1 nA maximum, quiescent current of 800 µA typical per amplifier, gain-bandwidth of 1 MHz typical and slew rate of 0.8 V/µs typical, over supplies from ±2 V to ±18 V. The selection point is DC precision at bipolar supply voltages: industrial signal conditioning, bridge and thermocouple front ends and precision control loops get microvolt-class offset without a chopper amplifier or a 5 V-only supply constraint. Selection advice: quote the UA/2K5 suffix in full - it fixes the SOIC-8 package, the precision grade and the reel quantity in a single string, and other suffixes of this family change at least one of the three. Ordering note: the plain OPA2277U code is the standard-grade sibling of this A-grade code, supplied in tubes of 75 in the same SOIC-8 package; the two codes are not interchangeable on a BOM line that specifies the A grade. Parameters verified against the TI OPA2277 datasheet SBOS079 and the TI part-details page.
