LTC2308IUF#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2308IUF#TRPBF is a low noise, 500ksps, 8-channel, 12-bit successive approximation register (SAR) analog-to-digital converter. It features an SPI/MICROWIRE compatible serial interface, an internal 2.5V reference, and a fully differential sample-and-hold circuit. The device operates from a single 5V supply, drawing 3.5mA at maximum sampling rate. Key electrical parameters include a SINAD of 73.3dB, THD of -89.5dB, and a maximum SCK frequency of 40MHz. It supports unipolar or bipolar input ranges and includes auto-shutdown modes for power reduction.
