FEATURES

DESCRIPTION

•

16-Bit Resolution

The ADS1209 is a two-channel, high-performance,

delta-sigma (ΔΣ) modulator with an 86dB dynamic

range, operating from a single +5V supply. The

differential inputs are ideal for direct connection to

signal sources in an industrial environment. With the

appropriate digital filter and modulator rate, the

device can be used to achieve 16-bit analog-to-digital

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

accuracy of 14 bits can be obtained with a digital filter

bandwidth of 20kHz at a modulator rate of 10MHz.

The ADS1209 is designed for use in high-resolution
