MAX5813/MAX5814/MAX5815
Ultra-Small, Quad-Channel, 8-/10-/12-Bit Buffered
Output DACs with Internal Reference and I2C Interface
General Description
The MAX5813/MAX5814/MAX5815 4-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
MAX5813/MAX5814/MAX5815 accept a wide supply
voltage range of 2.7V to 5.5V with extremely low power
(3mW) 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 MAX5813/MAX5814/MAX5815 have an I2C-compatible,
2-wire interface that operates at clock rates up to
400kHz. The DAC output is buffered and has a low sup-
ply current of less than 250FA per channel and a low
offset error of Q0.5mV (typ). On power-up, the MAX5813/
MAX5814/MAX5815 reset the DAC outputs to zero, pro-
viding 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 MAX5813/MAX5814/
MAX5815 allow simultaneous output updates using soft-
ware LOAD commands or the hardware load DAC logic
input (LDAC).
A clear logic input (CLR) allows the contents of the CODE
and the DAC registers to be cleared asynchronously and
sets the DAC outputs to zero. The MAX5813/MAX5814/
MAX5815 are available in a 14-pin TSSOP and an ultra-
small, 12-bump WLP package 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.
