OPA197IDBVR Description

The OPA197IDBVR is a 36-V operational amplifier from a new generation. These devices include rail-to-rail input/output, low offset (25 V, typical), low offset drift (0.25 V/°C, typ), and 10-MHz bandwidth, as well as excellent dc precision and ac performance. According to OPA197IDBVR datasheet, it is a durable, high-performance operational amplifier for high-voltage, industrial applications with unique features such as differential input-voltage range to the supply rail, high output current (65 mA), high capacitive load drive of up to 1 nF, and fast slew rate (20 V/s). The OPA197IDBVR op amps come in standard packaging and have a temperature range of –40°C to +125°C.
