AD7569JNZ

AD7569 is a complete, 8bit, analogue I/O system on a single monolithic chip. It contains a high speed successive approximation ADC with 2µs conversion time, a track/ hold with 200KHz bandwidth, a DAC and an output buffer amplifier with 1µs settling time. A temperature-compensated 1.25V bandgap reference provides a precision reference voltage for the ADC and the DAC. The AD7669 contains two DACs with output buffer amplifiers. Digital interfacing is via an 8bit I/O port and standard microprocessor control lines. Bus interface timing is extremely fast, allowing easy connection to all popular 8bit microprocessors. A separate start convert line controls the track/hold and ADC to give precise control of the sampling period. It is fabricated in linear-compatible CMOS (LC²MOS), an advanced, mixed technology process combining precision bipolar circuits with low power CMOS logic.
