ADS1204 Overview
Key Specifications
Package: VQFN
Pins: 32
Max Voltage (typical range): 5.5 V
Min Voltage (typical range): 2.7 V
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.
