General Description

The 16-bit CS5529 is a low-power, programmable ∆Σ ADC (Analog-to-Digital Converter), which includes coarse/fine charge buffers, a fourth-order ∆Σ modulator, a calibration microcontroller, a digital filter with programmable decimation rates, a 6-bit output latch, and a threewire serial interface. The ADC is designed to operate from single or dual analog supplies and a single digital supply.
