Analog Devices Inc. AD5721 Voltage Output DACs

Analog Devices AD5721 12-Bit Multiple Range Voltage Output Digital-to-Analog Converters (DACs) 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, these single-channel AD5721 DACs provide an easy-to-use, universal solution. Compatible with DSP and microcontroller interface standards, AD5721's serial interface operates at clock rates of up to 50MHz. Double buffering enables the asynchronous updating of the DAC output. ADI AD5721 DACs are ideal for industrial automation, instrumentation, data acquisition, open-/closed-loop servo control, process control, and programmable logic controllers.
