3 Description

The OPA202, OPA2202, and OPA4202 (OPAx202)

are a family of devices built on TI's industry-leading

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.

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.
