The DAC712 is a monolithic integrated-circuit, 16-bit All latches are level-triggered. Data present when the
D/A converter complete with 16-bit D/A converter enable inputs are logic '0' enter the latch. When the
switches and ladder network, voltage reference, enable inputs return to logic '1', the data are latched.
output amplifier, and microprocessor bus interface.
The CLR input resets both the input latch and the D/A
latch to give a bipolar zero output.
The DAC712 has double-buffered data latches. The
input data latch holds a 16-bit data word before
loading it into the second latch, the D/A latch. This
double-buffered organization permits simultaneous
update of several D/A converters. All digital control
inputs are active low. Refer to the block diagram of
Figure 8 .
