CS5372 Datasheet - Cirrus Logic

Description
The CS5371 and CS5372 are one- and two-channel, high dynamic range, fourth-order ∆Σ modulators intended for geophysical and sonar applications. Used in combination with the CS5376A or CS5378 digital filters, a unique high-resolution A/D measurement system results.
