The DAC7551IDRNT is an 1-channel 12-bit voltage-output Digital-to-analog Converter (DAC) with exceptional linearity and monotonicity and a proprietary architecture that minimizes glitch energy. The low-power DAC7551 operates from a single 2.7 to 5.5V supply. The DAC7551 output amplifiers can drive a 2kR, 200pF load rail-to-rail with 5μs settling time, the output range is set using an external voltage reference. The 3-wire serial interface operates at clock rates up to 50MHz and is compatible with SPI?, QSPI?, MICROWIRE? and DSP interface standards. The part incorporates a power-on-reset circuit to ensure that the DAC output powers up to 0V and remains there until a valid write cycle to the device takes place. The part contains a power-down feature that reduces the current consumption of the device to under 2μA. Small size and low-power operation make the DAC7551 ideally suited for battery-operated, portable applications.
