DESCRIPTION
The DAC725 is a dual 16-bit DAC, complete with
internal reference and output op amps. The DAC725 is
designed to interface to an 8-bit microprocessor bus,
but can also be interfaced to wider buses. The hybrid
construction minimizes the digital feedthrough typi-
cally associated with products that combine the digital
bus interface circuitry with high-accuracy analog cir-
cuitry.
The 16-bit data word is loaded into either of the DACs
in two 8-bit bytes per 16-bit word. The versatility of
the control lines allows the data word to be directed to
either DAC, in any order. The voltage-out DACs are
dedicated to a bipolar output voltage of ±10V. The
output is immediately set to 0V when the Clear com-
mand is given. This feature, combined with the bus
interfacing and complete DAC circuitry, makes the
DAC725 ideal for automatic test equipment, power
control, servo systems, and robotics applications.
