AD7847BR Description

Short technical summary and product information.

The AD7847BR is a 12-bit dual channel voltage output digital-to-analog converter (DAC) manufactured by Analog Devices. It utilizes an R-2R ladder architecture with an external reference input, providing a buffered voltage output. The device operates with dual power supplies (VDD from 14.25V to 15.75V, VSS from -14.25V to -15.75V) and features a parallel data interface for digital communication.

 

Key specifications include a settling time of 3 µs typical (5 µs maximum) to ±1/2 LSB, a slew rate of 11 V/µs typical, and a small signal bandwidth of 750 kHz. The DAC offers excellent linearity with ±1 LSB maximum INL and DNL (B version), and guaranteed monotonicity. It also features a glitch impulse of 10 nV·s and a total harmonic distortion of -88 dB typical.

 

The AD7847BR is suitable for applications requiring precise analog output control, such as process control, automatic test equipment, and industrial automation. The device is surface-mount packaged in a 24-pin SOIC (0.295" width) and operates over the industrial temperature range of -40°C to +85°C.
