Overview
The LTC2376IMS-18#TRPBF is a high-performance, 18-bit successive approximation register (SAR) analog-to-digital converter (ADC) produced by Analog Devices Inc. This device operates from a single 2.5V supply and is designed for low noise, low power, and high-speed applications. It features a fully differential input range with a reference voltage (VREF) that can range from 2.5V to 5.1V, making it ideal for applications requiring a wide dynamic range.
The LTC2376IMS-18#TRPBF achieves a signal-to-noise ratio (SNR) of 102dB and has a maximum integral nonlinearity (INL) of ±1.75LSB with no missing codes at 18 bits. It consumes only 3.4mW at a sampling rate of 250ksps and includes an auto power-down feature to reduce power dissipation during inactive periods.
