DAC7554IDGSR

12位四路，超低毛刺电压输出数位类比转换器 12-BIT, QUAD, ULTRALOW GLITCH, VOLTAGE OUTPUT DIGITAL-TO-ANALOG CONVERTER

DESCRIPON

The DAC7554 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 DAC7554 operates from a single 2.7-V to 5.5-V supply. The DAC7554 output amplifiers can drive a 2-kΩ, 200-pF load rail-to-rail with 5-µs settling time; the output range is set using an external voltage reference.
