The AD7847BR is a monolithic, single supply, low power, CMOS 16-bit digital to analog converter ( DAC ) which has an extended input range and comes in an 8-lead plastic package. Its superior performance, size and compatibility make it ideal for applications like data acquisition systems, industrial control systems, medical instrumentation, instrumentation and audio/visual systems. It is designed to work perfectly with both 8-bit and 16-bit microprocessors and microcontrollers.

The AD7847BR is a low power CMOS DAC with a very high output resolution. It can convert both 8-bit and 16-bit data into analog signals with up to 16-bit accuracy (0.1 μV) and a ±2V full scale output range. This makes it particularly well-suited for applications that require both high accuracy and a wide signal range. The AD7847BR has an extended input range (0 to Vss) and a low quiescent current of only 1.5 mA. It also has an adjustable startup current that can be set to any value between 0.1 mA and 0.8 mA. This allows users to optimize their applications for low power operation.

When it comes to working principle, the AD7847BR uses a bandgap reference to generate the required reference voltage. This reference voltage is then used to generate the +/-2V output. The AD7847BR has a parallel I/O interface and can be interfaced with both 8-bit and 16-bit microprocessors and microcontrollers. The data is clocked in on the rising edge of the clock signal and converted in the DAC on the falling edge of the clock signal. The output of the DAC is an analog signal that is linearly proportional to the digital input word.

The AD7847BR is an ideal solution for applications that require high accuracy, wide signal range and low power digital to analog conversion. Its low power and extended input range make it well-suited for portable medical instruments and instrumentation as well as data acquisition systems. Its compatibility with 8-bit and 16-bit microprocessors and microcontrollers make it a great choice for industrial control systems, medical instrumentation, instrumentation and audio/visual systems.
