Texas Instruments OPA188/OPA188-Q1 Precision Operational Amplifier
Texas Instruments OPA188/OPA188-Q1 Operational Amplifiers use TI proprietary auto-zeroing techniques to provide low offset voltage (25µV, max), and near zero-drift over time and temperature. This miniature, high-precision, low-quiescent current amplifier offers high input impedance and rail-to-rail output swing within 15mV of the rails.
The input common-mode range includes the negative rail. Either single or dual supplies can be used in the range of +4V to +36V (±2V to ±18V). The single version is available in the MicroSIZE SOT23-5, MSOP-8, and SO-8 packages. All versions are specified for operation from –40°C to +125°C. The OPA188-Q1 devices are AEC-Q100 qualified for automotive applications.
