DAC7552IRGTRG4

12 位、双路、超低毛刺脉冲、电压输出数模转换器 16-VQFN -40 to 105

DESCRIPON

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-kΩ, 200-pF load rail-to-rail with 5-µs settling time; the output range is set using an external voltage reference.
