DESCRIPTION

The ADS1254 is a precision, wide dynamic range, deltasigma,

Analog-to-Digital (A/D) converter with 24-bit resolution.

The delta-sigma architecture is used for wide dynamic

range and to ensure 24 bits of no missing codes performance.

An effective resolution of 19 bits (1.8ppm of rms

noise) is achieved for conversion rates up to 20kHz.

The ADS1254 is designed for high-resolution measurement

applications in cardiac diagnostics, smart transmitters, industrial

process control, weight scales, chromatography, and

portable instrumentation. The converter includes a flexible,

two-wire synchronous serial interface for low-cost isolation.

The ADS1254 is a multi-channel converter and is offered in

an SSOP-20 package.
