AD5744RCSUZ

AD5744RCSUZ is a quad, 14bit, serial input, bipolar voltage output DAC that operates from supply voltages of ±11.4V to ±16.5V. The AD5744R provides integrated output amplifiers, reference buffers, and proprietary power-up/power-down control circuitry. The part also features a digital I/O port, programmed via the serial interface, and an analogue temperature sensor. The part incorporates digital offset and gain adjust registers per channel. It is a high-performance converter that provides guaranteed monotonicity, integral nonlinearity (INL) of ±1LSB, low noise, and 10μs settling time. It includes an on chip 5V reference with a reference temperature coefficient of 10ppm/°C maximum. Applications include industrial automation, open-loop/closed-loop servo control, process control, data acquisition systems, automatic test equipment, automotive test and measurement, and high accuracy instrumentation.

• Integrated reference buffers, on-chip die temperature sensor
• Output control during power-up/brownout, programmable short-circuit protection
• Simultaneous updating via active-low LDAC, asynchronous active-low CLR to zero code
• Digital offset and gain adjust, logic output control pins
• DSP-/microcontroller-compatible serial interface, iCMOS process technology
• Relative accuracy is +1LSB maximum at (AVDD = 11.4V to 16.5V, AVSS = -11.4V to -16.5V)
• Differential nonlinearity is +1LSB maximum at (AVDD = 11.4V to 16.5V, AVSS = -11.4V to -16.5V)
• Output noise spectral density is 60nV/√Hz typical at (AVDD = 11.4V to 16.5V)
• Output voltage settling time is 8μs typical at (AVDD = 11.4V to 16.5V)
• Operating temperature range from -40°C to +85°C, 32-lead TQFP package
