Its proprietary architecture minimizes undesired transients such as code-to-code glitch and channel-to-channel crosstalk. The low-power DAC7552 operates from a single 2.7-V to 5.5-V supply. The DAC7552 output amplifiers can drive a 2-kΩ, 200-p F load rail-to-rail with 5-µs settling time; the output range is set using an external voltage reference. The 3-wire serial interface operates at clock rates up to 50 MHz and is patible with SPI, QSPI, Microwire™, and DSP interface standards. The outputs of all DACs may be updated simultaneously or sequentially. The parts incorporate a power-on-reset circuit to ensure that the DAC outputs power up to zero volts and remain there until a valid write cycle to the device takes place. The parts contain a power-down feature that reduces the current consumption of the device to under 2 µA. The small size and low-power operation makes the DAC7552 ideally suited for battery-operated portable applications. The power consumption is typically 1.5 m W at 5 V, 0.75 m W at 3 V, and reduces to 1 µW in power-down mode. The DAC7552 is available in a 16-lead QFN package and is specified over - 40°C to...
