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.
