Overview of OPA2187IDR
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.
