Product Summary
The DAC7554IDGSR is a quad-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 DAC7554IDGSR operates from a single 2.7-V to 5.5-V supply. The DAC7554IDGSR output amplifiers can drive a 2-kΩ, 200-pF 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 50 MHz and is compatible with SPI, QSPI, Microwire, and DSP interface standards. The outputs of the DAC7554IDGSR 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 con sumption of the device to under 1μA. The small size and low-power operation makes the DAC7554IDGSR ideally suited for battery-operated portable applications.
