ANALOG DEVICES AD7569 handbook

The AD7569/AD7669 is a complete, 8-bit, analog I/O system on a single monolithic chip. It contains a high speed successive approximation ADC with 2µs conversion time, a track/hold with 200 kHz bandwidth, a DAC and an output buffer ampli- fier with 1µs settling time. A temperature-compensated 1.25 V bandgap reference provides a precision reference voltage for the ADC and the DAC.
