OPA202 (正在供货)

采用 SOT23-5 封装的高精度、低噪声、低成本运算放大器

 

描述

The OPAx202 series is built on TI’s industry-leading precision super-β complementary bipolar semiconductor process which offers ultra-low flicker noise, low offset voltage, low offset voltage temperature drift, and excellent linearity with common-mode and power supply variation. The series offers an exceptional combination of DC precision, heavy capacitive load drive, and protection against external EMI, thermal, and short-circuit events.

Supply current is 580 µA at ±18 V. The OPAx202 series does not exhibit phase inversion, and the series is stable with high capacitive loads. The OPAx202 series is fully specified with a temperature range from –40°C to +105°C.
