Description

A new class of operational amplifiers with e-trim capability for 36-V systems is the OPA192IDBVT.

Rail-to-rail input/output, low offset (±5 μV, typ), low offset drift (±0.2 μV/°C, typ), 10-MHz bandwidth, and superb dc precision and ac performance are all features of these devices.

The OPA192IDBVT is a strong, high-performance operational amplifier for high-voltage industrial applications due to its distinctive features, which include differential input-voltage range to the supply rail, high output current (±65 mA), high capacitive load drive of up to 1 nF, and high slew rate (20 V/μs).

Op amps in the standard packaging with a temperature range of -40 to +125 degrees Celsius are called OPA192IDBVT.
