Texas Instruments OPA2188/OPA2188-Q1 Zero-Drift Op Amps

Texas Instruments OPA2188/OPA2188-Q1 Zero-Drift Operational Amplifiers (op amps) provide low offset voltage (25µV, max) and near zero-drift over time and temperature. TI OPA2188/OPA2188-Q1 miniature, high-precision, low quiescent current amplifiers offer high input impedance and rail-to-rail output swing within 15mV of the rails. These TI op amps are ideal for use in bridge amplifiers, strain gauges, test equipment, and more. The Texas Instruments OPA2188-Q1 devices are AEC-Q100 qualified for automotive applications.
