CS5378 Datasheet - Cirrus Logic

Description
The CS5378 is a multi-function digital filter utilizing a lowpower signal processing architecture to achieve efficient filtering for a delta-sigma-type modulator. By combining the CS5378 with a CS3301A/02A differential amplifier and a CS5373A modulator + test DAC, a synchronous high-resolution, self-testing, single-channel measurement system can be designed quickly and easily.
