The SDCRDAC24b is a 24-bit sigma-delta charge-redistribution digital-to-analog converter (DAC). It is designed to have high absolute accuracy, low flicker noise and low power consumption, and is robust against temperature variations and radiation. This makes the DAC ideally suited for demanding control applications in a wide variety of environments.
This IP is silicon proven.
