General Description

The ADS1204 is a four-channel, high-performance device, with four delta-sigma (ΔΣ) modulators with 100-dB dynamic range, operating from a single 5-V 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.
