DESCRIPTION

The ADS1251 is a precision, wide dynamic range, deltasigma,

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

operating from a single +5V supply. The delta-sigma

architecture features wide dynamic range, and 24 bits of no

missing code performance. Effective resolution of 19 bits

(1.5ppm of rms noise) is achieved at conversion rates up to

20kHz.

The ADS1251 is designed for high-resolution measurement

applications in cardiac diagnostics, smart transmitters, industrial

process control, weigh scales, chromatography, and

portable instrumentation. The converter includes a flexible,

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

The ADS1251 is a single-channel converter and is offered in

an SO-8 package. It is pin-compatible with the faster ADS1252

(41.7kHz data rate).
