DESCRIPTION
The OPAx188 series operational amplifiers use TI
proprietary auto-zeroing techniques to provide low
offset voltage (25 μV, max), 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 15 mV of the rails. The input common-mode
range includes the negative rail. Either single or dual
supplies can be used in the range of +4.0 V to +36 V
(±2 V to ±18 V).
The single version is available in the MicroSIZE
SOT23-5, MSOP-8, and SO-8 packages; the dual is
offered in MSOP-8 and SO-8 packages; the quad is
offered in SO-14 and TSSOP-14 packages. All
versions are specified for operation from –40°C to
+105°C.
