SBOS812H –OCTOBER 2017–REVISED MAY 2020  
OPAx202 Precision, Low-Noise, Heavy Capacitive Drive, 36-V Operational Amplifiers  
1 Features  
3 Description  
The OPA202, OPA2202, and OPA4202 (OPAx202)  
are a family of devices built on TI's industry-leading

Low offset voltage: 200 µV (maximum)  
Ultra-low drift: 1 µV/°C (maximum)  
precision  
super-beta,  
complementary,  
bipolar  
semiconductor process. This process offers ultra-low  
flicker noise, low offset voltage, low offset voltage  
temperature drift, and excellent linearity with  
common-mode and power-supply variation. These  
devices offer an exceptional combination of dc  
precision, heavy capacitive load drive, and protection  
against external EMI, thermal, and short-circuit  
events.

–
Quiescent current: 580 µA (typical)  
Gain-bandwidth product: 1 MHz  
Low input voltage noise: 9 nV/√Hz  
Ease of use, design simplicity:  
–
–
–
Heavy capacitive load drive: 5-µs settling time  
with 25 nF  
The supply current is 580 µA at ±18 V. The OPAx202  
do not exhibit phase inversion, and the series is  
stable with high capacitive loads. The OPAx202 are  
fully specified with a temperature range from –40°C  
to +105°C.  
Ultra-high input impedance: 3000 GΩ and  
0.5 pF  
EMI hardened, thermal, and short-circuit  
protection
