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.
