OPA4488DR

OPA4488DR is a Texas Instruments quad zero-drift operational amplifier in a 14-pin SOIC package, bringing chopper precision to a 48 V supply range (60 V absolute maximum) for industrial signal chains. Offset voltage is 7.5 µV maximum with 0.025 µV/°C maximum drift, while the ac side stays fast: 14 MHz gain bandwidth, 40 V/µs slew rate and 7.5 nV/√Hz broadband noise. CMRR and PSRR are 140 dB minimum, quiescent current is 1.5 mA per channel, and the MUX-friendly input architecture settles quickly after multiplexer switching transients, which is where zero-drift quads usually lose accuracy. Inputs include the negative rail and the output swings rail to rail, over -40°C to +125°C. Selection advice: the DR code is the SOIC-14 tape-and-reel variant; this family carries no I temperature-grade infix, so an OPA4488IDR offer is a mislabelled part, not a sibling code. For two channels instead of four, the OPA2486DR listed on this site is the dual counterpart. Parameters verified against Texas Instruments documentation.
