Nominal full-scale output range is ±10 V. The AD5744R provides integrated output amplifiers, reference buffers and proprietary power-up/powerdown control circuitry. The parts also feature a digital I/O port, which is programmed via the serial interface and an analog temperature sensor. The part incorporates digital offset and gain adjust registers per channel. The AD5744R is a high performance converter that offers guaranteed monotonicity, integral nonlinearity (INL) of ±1 LSB, low noise, and 10 μs settling time. The AD5744R includes an on-chip 5 V reference with a reference tempco of 10 ppm/°C maximum. During power-up (when the supply voltages are changing), VOUT is clamped to 0 V via a low impedance path. The AD5744R uses a serial interface that operates at clock rates of up to 30 MHz and is patible with DSP and microcontroller interface standards. Double buffering allows the simultaneous updating of all DACs. The input coding is programmable to either twos plement or offset binary formats. The asynchronous clear function clears all DAC registers to either bipolar zero or zero scale depending on the coding used....
