Product Summary

The AD7868AR is a complete 12-bit I/O system containing a DAC and an ADC . The AD7868AR is a successive approximation type with a track-and-hold amplifier having a combined throughput rate of 83 kHz. The AD7868AR has an output buffer amplifier with a settling time of 3 ms to 12 bits. Temperature compensated 3 V buried Zener references provide precision references for the DAC and ADC.
