DESCRIPTION

The ADS1205 is a two-channel, high-performance,

delta-sigma (ΔΣ) modulator with more than 98dB 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

codes. Effective resolution of 14 bits can be obtained with

a digital filter bandwidth of 40kHz at a modulator rate of

10MHz. The ADS1205 is designed for use in

high-resolution measurement applications including

current measurements, smart transmitters, industrial

process control, and resolvers. It is available in a QFN-24

(4x4) package.
