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
-40NC to +105NC extended industrial temperature range.
