AD5721RBRUZ

AD5721R is a single channel, 12-bit, serial input, voltage output, digital-to-analogue converter (DAC). It operate single supply voltages from +4.75V to +30V or dual supply voltages from −16.5V to 0V VSS and +4.7 V to +16.5V VDD. The integrated output amplifier, reference buffer, and reference provide a very easy to use, universal solution. The device use a serial interface that operates at clock rates of upto 50MHz and are compatible with DSP and microcontroller interface standards. Double buffering allows the asynchronous updating of the DAC output. The input coding is user-selectable twos complement or straight binary. The asynchronous reset function resets all registers to their default state. It is widely used in application such as industrial automation, instrumentation, data acquisition, open-/closed-loop servo control, process control, programmable logic controllers etc.
