OPA187 - 1µV Vos, 0.005µV/°C, Rail-to-Rail Output, Low-Power 36V Zero-Drift Operational Amplifier

Updated : 2020-01-09 14:18:19
Description

The OPAx187 series operational amplifiers use auto-zeroing techniques to simultaneouslyprovide 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 outputswing within 5 mV of the rails into high-impedance loads. The input common-mode range includes thenegative 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 of the OPAx187 device is available in Microsize 8-pin VSSOP, 5-pinSOT-23, and 8-pin SOIC packages. The dual version is offered in 8-pinVSSOP and 8-pin SOIC packages. The quad version isoffered in 14-pin SOIC, 14-pin TSSOP, and 16-pin WQFN packages. All versions are specified foroperation from –40°C to +125°C.
