Analog Devices Inc. AD5761 16-Bit Multiple Range Voltage Output DACs

Analog Devices AD5761/R 16-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, and power-up/power-down control circuitry, the single-channel AD5761/R DACs provide an easy-to-use, universal solution.

Compatible with DSP and microcontroller interface standards, AD5761/R'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. The AD5761R version provides a typical low drift 2.5V reference of ±2ppm/°C. AD5761/R DACs deliver guaranteed monotonicity, integral nonlinearity (INL) of ±2LSB maximum, 35nV/√Hz noise, and 7.5μs settling time on selected ranges.

Operating to specifications over the −40°C to +125°C industrial temperature range, the AD5761/R multiple range voltage output DACs are ideal for industrial automation, instrumentation, data acquisition, open-/closed-loop servo control, process control, and programmable logic controllers.
