DAC7552 说明

The DAC7552 is a 12-bit, dual-channel, voltage-output 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-V to 5.5-V supply. The DAC7552 output amplifiers can drive a 2-Ω, 200-pF 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 compatible 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.
