Image of Texas Instruments' OPA2188 Zero-Drift Operational Amplifier Texas Instruments' OPA2188 series operational amplifiers use TI proprietary auto-zeroing techniques to provide low offset voltage (25 µV, max), and near zero-drift over time and temperature. These miniature, high-precision, low quiescent current amplifiers offer high input impedance and rail-to-rail output swing within 15 mV of the rails. The input common-mode range includes the negative rail. Either single or dual supplies can be used in the range of +4.0 V to +36 V (±2 V to ±18 V). The single version is available in the MicroSIZE SOT23-5, MSOP-8, and SO-8 packages; the dual is offered in MSOP-8 and SO-8 packages; the quad is offered in SO-14 and TSSOP-14 packages. All versions are specified for operation from -40°C to +105°C.
