DESCRIPTION

The ADS1201 is a precision, 130dB dynamic range,

delta-sigma (DS) 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.

The ADS1201 is designed for use in high resolution

measurement applications including smart transmitters,

industrial process control, weigh scales, chromatography,

and portable instrumentation. It is available

in a 16-lead SOIC package.
