Four 1-Bit, 10MHz, 2nd-Order

Delta-Sigma Modulators

FEATURES

DESCRIPTION

•

16-Bit Resolution

The ADS1204 is a four-channel, high-performance

device, with four delta-sigma (ΔΣ) 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 (5×5) package.
