The AD5754RBREZ is a Complete Quad 16-bit Serial Input Unipolar/Bipolar Voltage Output DAC with internal reference that operates from single supply voltages of +4.5V up to +16.5V or dual supply voltages from ±4.5V up to ±16.5V. Integrated output amplifiers, reference buffers and proprietary power-up/power-down control circuitry are also provided. The parts offer guaranteed monotonicity, integral nonlinearity (INL) of ±16 LSB maximum, low noise, 10μs typical settling time and an on-chip +2.5V reference. It uses a serial interface that operates at clock rates up to 30MHz and is compatible with DSP and microcontroller interface standards. Double buffering allows the simultaneous updating of all DACs. The input coding is user-selectable twos complement or offset binary for a bipolar output (depending on the state of Pin BIN/2sCOMP) and straight binary for a unipolar output.
