DAC7552IRGTT Datasheet PDF - TI

●The DAC7552IRGTT is a 2-channel 12-bit voltage-output Digital-to-analog Converter (DAC) with exceptional linearity and monotonicity. 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 to 5.5V supply. The DAC7552 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 outputs of DAC may be updated simultaneously or sequentially. The part incorporates 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 2µA.
