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
