ADS1201

High Dynamic Range

DELTA-SIGMA MODULATOR

DESCRIPTION

FEATURES

● 130dB DYNAMIC RANGE

The ADS1201 is a precision, 130dB dynamic range,

delta-sigma (∆Σ) modulator operating from a single

+5V supply. The differential inputs are ideal for direct

connection to transducers or low level signals. With

the appropriate digital filter and modulator rate, the

device can be used to achieve 24-bit analog-to-digital

(A/D) conversion with no missing codes. Effective

resolution of 20 bits can be maintained with a digital

filter bandwidth of 1kHz at a modulator rate of 320kHz.

● FULLY DIFFERENTIAL INPUT

● TWO-WIRE INTERFACE

● INTERNAL/EXTERNAL REFERENCE

● ON-CHIP SWITCHES FOR CALIBRATION

APPLICATIONS

● INDUSTRIAL PROCESS CONTROL

● INSTRUMENTATION

The ADS1201 is designed for use in high resolution

measurement applications including smart transmit-

ters, industrial process control, weigh scales, chroma-

tography, and portable instrumentation. It is available

in a 16-lead SOIC package.

● SMART TRANSMITTERS

● PORTABLE INSTRUMENTS

● WEIGH SCALES

● PRESSURE TRANSDUCERS
