24-bit Sigma Delta Charge-Redistribution DAC (High bandwidth)
The 24-bit Sigma Delta Charge-Redistribution DAC is designed to have high absolute accuracy, low noise and low power consumption, and it is robust against temperature variations. This 24-bit Sigma Delta Charge-Redistribution DAC is ideally suited for high-performance audio as well as demanding control applications in a wide variety of environments.
The 24-bit Sigma Delta Charge-Redistribution DAC is based on the SDCRDAC24b, but this version is not radiation hardened. Instead, the 24-bit Sigma Delta Charge-Redistribution DAC has increased bandwidth, increased temperature stability and lower power consumption.
This product is silicon-verified.
