The MAX5723/MAX5724/MAX5725 8-channel, low-power,

8-/10-/12-bit, voltage-output digital-to-analog converters

(DACs) include output buffers and an internal 3ppm/°C

reference that is selectable to be 2.048V, 2.500V, or

4.096V. The MAX5723/MAX5724/MAX5725 accept a

wide supply voltage range of 2.7V to 5.5V with extremely

low power (6mW) consumption to accommodate most

low-voltage applications. A precision external reference

input allows rail-to-rail operation and presents a 100kI

(typ) load to an external reference.

The MAX5723/MAX5724/MAX5725 have a fast 50MHz,

4-wire SPI/QSPI™/MICROWIRE/DSP-compatible serial

interface that operates at clock rates up to 50MHz. The

DAC output is buffered and has a low supply current

of less than 250FA per channel and a low offset error

Q0.5mV

(typ). On power-up, the MAX5723/MAX5724/

MAX5725 reset the DAC outputs to zero or midscale

based on the status of M/Z logic input, providing flex-

ibility for a variety of control applications. The internal

reference is initially powered down to allow use of an

external reference. The MAX5723/MAX5724/MAX5725

allow simultaneous output updates using software LOAD

commands or the hardware load DAC logic input (LDAC).

The MAX5723/MAX5724/MAX5725 feature a program-

mable watchdog function which can be enabled to moni-

tor the I/O interface for activity and integrity.

A clear logic input (CLR) allows the contents of the CODE

and the DAC registers to be cleared asynchronously and

simultaneously sets the DAC outputs to the program-

mable default value. The MAX5723/MAX5724/MAX5725

are available in a 20-pin TSSOP and an ultra-small,

20-bump WLP package and are specified over the -40NC

to +125NC temperature range.
