The AD7868AR is a complete 12-bit analog I/O system from Analog Devices. It integrates a 12-bit successive approximation ADC with track-and-hold and a 12-bit DAC with output buffer amplifier. The ADC achieves a throughput rate of 83 kHz with a typical signal-to-noise ratio of 72 dB. The DAC settles to 12-bit accuracy in 3 µs. Both ADC and DAC use on-chip temperature compensated 3V buried Zener references. The serial interface minimizes pin count, supporting standard control signals for DSP machines. The device operates from ±5V dual supplies and dissipates 130 mW typical. The analog input/output range is ±3V. The AD7868AR is offered in a 28-pin SOIC package for surface mount applications. It is suitable for digital signal processing, speech recognition, spectrum analysis, and high speed modems.
The AD7868AR requires dual ±5V supplies: VDD from 4.75V to 5.25V and VSS of -5V nominal.
The AD7868AR is available in a 28-SOIC (0.295", 7.50mm Width) surface-mount package.
The AD7868AR is listed as RoHS3 compliant, but this information is unverified.
The AD7868AR has a 12-bit resolution for both ADC and DAC.
The ADC sampling rate is 83 kHz typical.
The AD7868AR uses a serial interface compatible with TTL/CMOS logic levels.
130 mW typical.
