EVALUATION KIT AVAILABLE
14-/16-Bit, Low-Power, Buffered Output,
Rail-to-Rail DACs with SPI Interface
General Description
The MAX5214/MAX5216 are pin-compatible, 14-bit and
16-bit digital-to-analog converters (DACs). The MAX5214/
MAX5216 are single-channel, low-power, buffered volt-
age-output DACs. The devices use a precision external
reference applied through the high resistance input for
rail-to-rail operation and low system power consumption.
The MAX5214/MAX5216 accept a wide 2.7V to 5.5V sup-
ply voltage range. Power consumption is extremely low
to accommodate most low-power and low-voltage appli-
cations. These devices feature a 3-wire SPI-/QSPI™-/
MICROWIRE-/DSP-compatible serial interface to save
board space and to reduce the complexity in isolated
applications. The MAX5214/MAX5216 minimize the digi-
tal noise feedthrough from input to output with SCLK and
DIN input buffers powered down after completion of each
serial input frame. On power-up, the MAX5214/MAX5216
reset the DAC output to zero, providing additional safety
for applications that drive valves or other transducers that
need to be off on power-up. The DAC output is buffered
resulting in a low supply current of 80µA (max) and a low
offset error of ±0.25mV. A zero level applied to the CLR
pin asynchronously clears the contents of the input and
DAC registers and sets the DAC output to zero indepen-
dent of the serial interface. The MAX5214/MAX5216 are
available in an ultra-small (3mm x 5mm), 8-pin µMAX®
package and are specified over the -40°C to +105°C
extended industrial temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation
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.
