The AD7804/AD7808 are quad/octal 10-bit with serial load
Digital-to-analog converters; The AD7805/AD7809 are quad/octal 10-bit digital-to-analog converters with parallel loading, respectively. These devices operate from +3.3 V to +5 V (±10%) supplies and contain an on-chip reference. The above DAC provides V

BIASAcquired internally. On-chip control registers include a system control register and multiple channel control registers. System control registers control all DACs in the package, and channel control registers control individual DACs. With an on-chip subDAC, the complete transfer function of each DAC can be offset by V
BIAS。 All DACs are configured with double-buffered data inputs, allowing all analog outputs to be updated simultaneously with asynchronous LDAC inputs.
