Analog Devices Inc. AD5721R Voltage Output DACs

Analog Devices AD5721R 12-Bit Multiple Range Voltage Output Digital-to-Analog Converters (DACs) are serial input, voltage output DACs that operate from single supply voltages of 4.75V-30V or dual supply voltages of -16.5V to 0V VSS and 4.75V-16.5V VDD. With its integrated output amplifier, reference buffer, the single-channel AD5721R DACs provide an easy-to-use, universal solution.

Compatible with DSP and microcontroller interface standards, AD5721R's serial interface operates at clock rates of up to 50MHz. Double buffering enables the asynchronous updating of the DAC output. User-selectable functions include twos complement or straight binary input coding and output range via the RA[2:0] bits in the control register.

Eight software-programmable output ranges are available including 0V to 5V, 0V to 10V, 0V to 16V, 0V to 20V, ±3V, ±5V, ±10V, −2.5V to +7.5V with 5% over range. Operating to specifications over the -40°C to +125°C industrial temperature range, the AD5721R DACs are ideal for industrial automation, instrumentation, data acquisition, open-/closed-loop servo control, process control, and programmable logic controllers.
