LT6600IS8-20#PBF

Instrumentation, Op Amps, Buffer Amps Overview

The LT6600IS8-20#PBF is a fully differential amplifier integrated with a fourth-order 20MHz lowpass filter. It operates on single 3V, 5V or dual ±5V supplies within the -40°C to 85°C industrial temperature range. The device provides programmable differential gain via two external resistors and features an adjustable output common mode voltage. It delivers a typical signal-to-noise ratio of 76dB at unity gain with a 3V supply.

Instrumentation, Op Amps, Buffer Amps FAQ

How is the differential gain programmed?

The differential gain is set by two equal external resistors connected to the input pins, calculated as 402Ω divided by the resistance value.

What is the function of Pin 2?

Pin 2 is the VOCM input that programs the DC common mode reference voltage for the second filter stage and determines the differential output common mode voltage.
