General Description

The MAX5839 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 +14V/-9V supplies. Its bipolar output

voltage swing ranges from +9V to -4V and is achieved

with no external components. The MAX5839 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 MAX5839 oper-

ates within the following voltage ranges: V

= +7V to

+14V, V

= -5V to -9V, and V

= +4.75V to +5.25V.

The MAX5839 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

. All other logic inputs are TTL/CMOS compatible.

The “A” grade of the MAX5839 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.
