14-/16-Bit, Low-Power,
High-Performance, Buffered Single DACs
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, buff-
ered voltage-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 5.25V supply voltage range. Power consump-
tion is extremely low to accommodate most low-power
and low-voltage applications. These devices feature a
3-wire SPIK-/QSPIK-/MICROWIREK-/DSP-compatible
serial interface to save board space and to reduce
the complexity in isolated applications. The MAX5214/
MAX5216 minimize the digital noise feedthrough from
input to output with SCLK and DIN input buffers pow-
ered down after completion of each serial input frame.
On power-up, the MAX5214/MAX5216 reset the DAC
output to zero, providing additional safety for applica-
tions 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 80FA (max) and
a low offset error of
Q0.25mV.
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 independent of the serial interface. The MAX5214/
MAX5216 are available in an ultra-small (3mm x 3mm),
8-pin
FMAX
®
package and are specified over the
-40NC to +105NC extended industrial temperature range.

Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-
layer board. For detailed information on package thermal considerations, refer to

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.
