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 amplifier can drive a 2 kW, 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. The parts contain a power down feature that reduces the current consumption of the device to under 1 μA.
