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.
The AD7869 is a complete 14-bit analog input/output system containing a 14-bit successive approximation ADC with a track-and-hold amplifier and a 14-bit DAC with an output buffer amplifier. It features an on-chip 3V temperature-compensated buried Zener reference for both the ADC and DAC, minimizing external component requirements. The device operates from ±5V power supplies with an analog input/output range of ±3V and is available in 24-pin DIP and 28-pin SOIC packages.
