FEATURES
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
2
•
•
•
Low Offset Voltage: 25 μV (max)
Zero-Drift: 0.03 μV/°C
Low Noise: 8.8 nV/√Hz
0.1-Hz to 10-Hz Noise: 0.25 µVPP
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).

Excellent DC Precision:
PSRR: 142 dB
CMRR: 146 dB
Open-Loop Gain: 136 dB

•
Gain Bandwidth: 2 MHz
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.
Quiescent Current: 475 μA (max)
Wide Supply Range: ±2 V to ±18 V
