LT1997IMS-2#TRPBF

Instrumentation, Op Amps, Buffer Amps Overview

The LT1997IMS-2#TRPBF is a precision attenuating funnel amplifier in a 16-lead MSOP package. It integrates a high-voltage operational amplifier with highly matched internal resistors to translate large differential signals into low voltage ranges compatible with ADCs. The device offers three pin-selectable gain options of 0.1, 0.2, and 0.25, which can be combined for gains between 0.0455 and 0.55. It supports a wide input common-mode voltage range up to ±255V and operates on supply voltages from 3.3V to 50V. Key specifications include a maximum gain error of 0.006%, a minimum CMRR of 105dB, and a shutdown current of 20µA.
