OPA187, OPA2187, OPA4187 SBOS807E – DECEMBER 2016 – REVISED MAY 2020 OPAx187 0.001-µV/°C Drift, Low Power, Rail-to-Rail Output 36-V Operational Amplifiers Zero-Drift Series 1 1 Features 1 • Low offset voltage: 10 µV (maximum) • Zero drift: 0.001 µV/°C • Low noise: 15 nV/ √Hz • PSRR: 160 dB • CMRR: 140 dB • AOL: 160 dB • Quiescent Current: 100 µA • Wide supply voltage: ±2.25 V to ±18 V • Rail-to-rail output operation • Input includes negative rail • Low bias current: 100 pA (typical) • EMI filtered inputs • Microsize packages 2 Applications • Analog input module • Mixed module (AI, AO, DI, DO) • Flow transmitter • Pressure transmitter • Test and measurement • Semiconductor test • Semiconductor manufacturing • Process analytics (pH, gas, concentration, force, and humidity) 3 Description The OPAx187 series operational amplifiers use auto- zeroing techniques to simultaneously provide low- offset voltage (1 µV), 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 5 mV of the rails into high-impedance loads. The input common-mode range includes the negative rail. Either single or dual supplies can be used in the range of 4.5 V to 36 V (±2.25 V to ±18 V). The single version OPAx187 device is available in microsize 8-pin VSSOP, 5-pin SOT-23, and 8-pin SOIC packages. The dual version is offered in 8-pin VSSOP and 8-pin SOIC packages. The quad version is offered in 14-pin SOIC, 14-pin TSSOP, and 16-pin WQFN packages. All versions are specified for operation from –40°C to +125°C.
