Analog Devices LTC6363 family of high-precision, low-power differential amplifiers have rail-to-rail outputs with linearity and noise optimized to drive high-resolution SAR ADCs.

This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.

ADI LTC6363 Differential Amplifiers 

Analog Devices LTC6363 family of high-precision, low-power differential amplifiers have rail-to-rail outputs with linearity and noise optimized to drive high-resolution SAR ADCs.  

LTC6363 amplifiers are available in variants with the gain set by external resistors or with fixed gain using precision laser-trimmed on-chip resistors. The devices have low input-referred noise, offset voltage, gain error and drift, as well as a high common mode rejection for high-precision applications.  

The amplifiers have a typical active current consumption of 1.7mA at 3V and 20µA in shutdown mode, enabling use in battery-powered applications. LTC6363 amplifiers can operate from a 2.8V to 11V supply and are available in compact MSOP and DFN packages.
