Combining \u00b1100\u00b5V offset voltage, 8nV\/\u221aHz input voltage noise, and 10pA bias current, it delivers outstanding precision for signal conditioning in measurement and medical applications. The rail-to-rail output stage maximizes dynamic range, while the 4V-36V supply range supports both single-supply and split-supply configurations.","working_principle":"The OPA2170AIDCUR uses a complementary bipolar input stage with chopper-free architecture to achieve \u00b1100\u00b5V typical offset voltage without the clock noise associated with zero-drift amplifiers. The rail-to-rail output stage uses a common-emitter configuration that swings to within millivolts of the supply rails, maximizing output dynamic range. The 3MHz gain bandwidth and 1.5V\/\u00b5s slew rate provide adequate bandwidth for precision signal conditioning up to the 100kHz range. EMI filtering on the inputs rejects high-frequency interference common in industrial environments.","pin_description":"
