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.
