AD7688 16-Bit PulSAR Differential ADC Data Sheet
The AD7688 is a 16-bit, charge redistribution, successive approximation analog-to-digital converter (ADC) that operates from a single 5 V power supply. It features a proprietary serial interface compatible with SPI, QSPI, MICROWIRE, and DSP protocols, allowing for daisy-chaining multiple devices. The device includes an internal conversion clock and a low noise, wide bandwidth track-and-hold circuit.
