Octal, 13-Bit Voltage-Output DAC
with Parallel Interface
General Description
The MAX5270 contains eight 13-bit, voltage-output digi-
tal-to-analog converters (DACs). On-chip precision out-
put amplifiers provide the voltage outputs. The device
operates from +12V/-12V supplies. Its output voltage
swing ranges from 0V to +8.192V and is achieved with
no external components. The MAX5270 has three pairs
of differential reference inputs; two of these pairs are
connected to two DACs each, and a third pair is con-
nected to four DACs. The references are independently
controlled, providing different full-scale output voltages
to the respective DACs. The MAX5270 operates within
the following voltage ranges: VDD = +11.4V to +12.6V,
VSS = -11.4V to -12.6V, and VCC = +4.75V to +5.25V.
The MAX5270 features double-buffered interface logic
with a 13-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
VDD. All other logic inputs are TTL/CMOS compatible.
The “A” grade of the MAX5270 has a maximum INL of
±2LSBs, while the “B” grade has a maximum INL of
±4LSBs. Both grades are available in 44-pin MQFP
packages.
