GENERAL DESCRIPTION
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
