CS5181 Datasheet (Cirrus Logic) - Modulator & 400 kHz to 625 kHz 16-Bit ADC

CS5181, Modulator & 400 kHz to 625 kHz 16-Bit ADC

CS5181 is a fully calibrated high-speed ∆Σ analog-todigital converter, capable of 625 kSamples/second output word rate (OWR).

The OWR scales with the master clock.

It consists of a 5th order ∆Σ modulator, decimation filter, and serial interface.

The chip can use the 2.375 V on-chip voltage reference
