AD7809:  +3.3 V to +5 V Quad/Octal 10-Bit DAC

Product Details

The AD7804/AD7808 are quad/octal 10-bit digital-to-analog converters, with serial load capabilities, while the AD7805/AD7809 are quad/octal 10-bit digital-to-analog converters with parallel load capabilities. These parts operate from a +3.3 V to +5 V (10%) power supply and incorporates an on-chip reference. These DACs provide output signals in the form of VBIAS VSWING. VSWING is derived internally from VBIAS. On-chip control registers include a system control register and channel control registers. The system control register has control over all DACs in the package. The channel control registers allow individual control of DACs. The complete transfer function of each individual DAC can be shifted around the VBIAS point using an on-chip Sub DAC. All DACs contain double buffered data inputs, which allow all analog outputs to be simultaneously updated using the asynchronous LDAC input.
