The OPA188operational amplifier uses TI’s proprietaryauto-zeroing techniques toprovide low offset voltage (25-µV maximum) and near zero-drift over time and temperature. This miniature, high-precision,low-quiescent current amplifier offers high input impedanceand rail-to-rail output swing within 15 mV of the rails. The input common-mode range includes thenegative rail. Either single or dual supplies can be used in the range from 4 V to 36 V (±2 V to±18 V).
The single version is available in the MicroSIZE SOT-23-5, MSOP-8, and SO-8 packages. All versions are specifiedfor operation from –40°C to +125°C.
