ADI LTC2376CDE-18#TRPBF

Overview

The LTC2376CDE-18#PBF is a low noise, low power, high speed 18-bit successive approximation register (SAR) ADC. Operating from a 2.5V supply, the LTC2376CDE-18#PBF has a ±VREF fully differential input range with VREF ranging from 2.5V to 5.1V. The LTC2376CDE-18#PBF consumes only 3.4mW and achieves ±1.75LSB INL maximum, no missing codes at 18 bits with 102dB SNR.

The LTC2376CDE-18#PBF features a unique digital gain compression (DGC) function, which eliminates the driver amplifier’s negative supply while preserving the full resolution of the ADC. When enabled, the ADC performs a digital scaling function that maps zero-scale code from 0V to 0.1 • VREF and full-scale code from VREF to 0.9 • VREF. For a typical reference voltage of 5V, the full-scale input range is now 0.5V to 4.5V, which provides adequate headroom for powering the driving amplifier from a single 5.5V supply.
