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.
