General Description
The MAX5264 contains eight 14-bit, voltage-output digi-
tal-to-analog converters (DACs). On-chip precision out-
put amplifiers provide the voltage outputs. The device
operates from +14V/-9V supplies. Its bipolar output
voltage swing ranges from +9V to -4V and is achieved
with no external components. The MAX5264 has three
pairs of differential reference inputs; two of these pairs
are connected to two DACs each, and a third pair is
connected to four DACs. The references are indepen-
dently controlled, providing different full-scale output
voltages to the respective DACs. The MAX5264 oper-
ates within the following voltage ranges: V
+14V, V
= -5V to -9V, and V
= +4.75V to +5.25V.

The MAX5264 features double-buffered interface logic
with a 14-bit parallel data bus. Each DAC has an input
latch and a DAC latch. Data in the DAC latch sets the
output voltage. The eight input latches are addressed
with three address lines. Data is loaded to the input
latch with a single write instruction. An asynchronous
load input (LD) transfers data from the input latch to the
DAC latch. The LD input controls all DACs; therefore, all
DACs can be updated simultaneously by asserting the
LD pin.
An asynchronous CLR input sets the output of all eight
DACs to the respective DUTGND input of the op amp.
Note that CLR is a CMOS input, which is powered by
V
. All other logic inputs are TTL/CMOS compatible.
DD
The “A” grade of the MAX5264 has a maximum INL of
±4LSBs, while the “B” grade has a maximum INL of
±8LSBs. Both grades are available in 44-pin MQFP
packages.
