MAX5803/MAX5804/MAX5805

C Interface
General Description
The MAX5803/MAX5804/MAX5805 single-channel, low-
power, 8-/10-/12-bit, voltage-output this is an addition
to content 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 MAX5803/MAX5804/
MAX5805 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 MAX5803/MAX5804/MAX5805 have an I
2
C-
compatible, 2-wire interface that operates at clock rates
up to 450kHz. The DAC output is buffered and has
a low supply current of 155FA (typical at 3.5V) and a
low offset error of
Q0.5mV
(typical). On power-up, the
MAX5803/MAX5804/MAX5805 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 MAX5803/MAX5804/MAX5805 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 MAX5803/MAX5804/MAX5805 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.
