FEATURES

DESCRIPTION

16-Bit Resolution

The ADS1204 is a four-channel, high-performance device,

with four delta-sigma (∆Σ) modulators with 100dB dynamic

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

inputs are ideal for direct connection to transducers 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

code. Effective resolution of 12 bits can be obtained with

a digital filter data rate of 160kHz at a modulator rate of

10MHz. The ADS1204 is designed for use in medium- to

high-resolution measurement applications including

current measurements, smart transmitters, industrial

process control, weight scales, chromatography, and

portable instrumentation. It is available in a QFN-32 (5x5)

package.
