AD7847AR Description

Short technical summary and product information.

The AD7847AR is a 12-bit, dual-channel digital-to-analog converter (DAC) from Analog Devices. It utilizes an R-2R architecture with voltage-buffered outputs, providing a full-scale output range determined by the external reference voltage. The device features a parallel interface for data loading and offers a maximum settling time of 5 µs to ±1/2 LSB.

 

Key electrical specifications include integral nonlinearity (INL) of ±1 LSB max and differential nonlinearity (DNL) of ±1 LSB max, ensuring monotonic operation over the entire temperature range. The DAC provides a slew rate of 11 V/µs typical, low glitch energy of 10 nV·s, and a unity gain bandwidth of 750 kHz. It is designed for dual supply operation from ±14.25 V to ±15.75 V.

 

The AD7847AR is housed in a surface-mount 24-SOIC package (0.295 inch, 7.50 mm width) and operates over an industrial temperature range of -40°C to +85°C. It is suitable for applications requiring precise voltage output generation, such as process control, waveform generation, and data acquisition systems.
