Texas Instruments' OPA202 device is built on the industry-leading precision super-β complementary bipolar semiconductor process and offers ultra-low flicker noise, low offset voltage, low offset voltage temperature drift, and excellent linearity with common-mode and power-supply variation. The device offers an exceptional combination of DC precision, heavy capacitive load drive, and protection against external EMI, thermal, and short-circuit events.
The op-amp offers a supply current of 580 µA at ±18 V. The OPA202 device does not exhibit phase inversion and it is stable with high capacitive loads. The OPA202 is fully specified with a temperature range from -40°C to +105°C.
