OPA202, OPA2202, OPA4202
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

Precision super-beta performance:
–
–
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.

•
Excellent efficiency:
–
–
–
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
