GENERAL DESCRIPTION
The AD7869 is a complete 14-bit I/O system containing a DAC and an ADC. The ADC is a successive approximation type with a track-and-hold amplifier, having a combined throughput rate of 83 kHz. The DAC has an output buffer amplifier with a settling time of 4 µs to 14 bits. Temperature compensated 3 V buried Zener references provide precision references for the DAC and ADC.
