Micropower instrumentation amp for precision sensor front-ends
It draws 175 µA supply current while delivering a 200 kHz -3dB bandwidth — a combination that suits battery-powered bridge, strain-gauge, and thermocouple interfaces where every microamp counts.
Supply flexibility and signal swing
The supply span covers 2.7 V to 36 V, which means the same BOM line works on a single 3.3 V rail for portable gear or a ±15 V industrial supply without a local regulator. The 0.4V/µs slew rate limits the output to slow-changing signals — expect full-scale settling in the tens-of-microseconds range, consistent with the 200 kHz bandwidth.
Housed in an 8-VSSOP (3.00 mm width, 0.118-inch pitch) — the same footprint as a standard MSOP-8. Surface-mount assembly with Tape & Reel or Cut Tape shipping options.
