The OPAx187 series operational amplifiers use autozeroing techniques to simultaneously provide lowoffset 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.
