LTC2482CDD#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2482CDD#TRPBF is a 16-bit delta-sigma analog-to-digital converter featuring patented Easy Drive technology for automatic differential input current cancellation. It operates on a single supply voltage ranging from 2.7V to 5.5V and includes an internal oscillator, eliminating the need for external crystals. The device provides rail-to-rail input capability with zero differential input current, allowing direct digitization of high-impedance sensors. Key electrical specifications include 600nV RMS noise independent of VREF, 2ppm integral nonlinearity (INL) with no missing codes, and simultaneous 50Hz/60Hz line frequency rejection. It utilizes a 3-wire SPI interface and is housed in a compact 10-lead 3mm x 3mm DFN package.
