MAX5703/MAX5704/MAX5705
Ultra-Small, Single-Channel, 8-/10-/12-Bit Buffered Output
Voltage DACs with Internal Reference and SPI Interface
General Description
The MAX5703/MAX5704/MAX5705 single-channel, low-
power, 8-/10-/12-bit, voltage-output digital-to-analog
converters (DACs) include output buffers and an internal
reference that is selectable to be 2.048V, 2.500V, or
4.096V. The MAX5703/MAX5704/MAX5705 accept a
wide supply voltage range of 2.7V to 5.5V with extremely
low power (< 1mW) 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 MAX5703/MAX5704/MAX5705 have a 50MHz,
3-wire SPI/QSPI™/MICROWIRE®/DSP-compatible serial
interface. The DAC output is buffered and has a low
supply current of 155FA (typical at 3V) and a low offset
error of
Q0.5mV
(typical). On power-up, the MAX5703/
MAX5704/MAX5705 reset the DAC outputs to zero,
providing additional safety for applications that drive
valves or other transducers which need to be off on
power-up. The internal reference is initially powered
down to allow use of an external reference.
The MAX5703/MAX5704/MAX5705 include a user-
configurable active-low asynchronous input,
AUX
for
additional flexibility. This input can be programmed to
asynchronously clear (CLR) or temporarily gate (GATE) the
DAC output to a user-programmable value. A dedicated
active-low asynchronous
LDAC
input is also included. This
allows simultaneous output updates of multiple devices.
The MAX5703/MAX5704/MAX5705 are available in 10-pin
TDFN/µMAX
M
packages and are specified over the -40NC
to +125NC temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional opera-
tion of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
