a LC2MOS
Quad 14-Bit DAC
AD7836
GENERAL DESCRIPTION FEATURES
Four 14-Bit DACs in One Package
Voltage Outputs
Separate Offset Adjust for Each Output
Reference Range of 5 V
Maximum Output Voltage Range of 10 V
Clear Function to User-Defined Code
44-Pin MQFP Package The AD7836 contains four 14-bit DACs on one monolithic
chip. It has output voltages with a full-scale range of ± 10 V
from reference voltages of ± 5 V.
The AD7836 accepts 14-bit parallel loaded data from the external bus into one of the input latches under the control of the
WR, CS and DAC channel address pins, A0–A2.
The DAC outputs are updated individually, on reception of new
data. In addition, the SEL input can be used to apply the user
programmed value in DAC Register E to all DACs, thus setting
all DAC output voltages to the same level. The contents of the
DAC data registers are not affected by the SEL input. APPLICATIONS
