MAX5723/MAX5724/MAX5725
Ultra-Small, Octal-Channel, 8-/10-/12-Bit Buffered
Output DACs with Internal Reference and SPI Interface
General Description
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
of 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.
