General Description
The MAX5222 contains two 8-bit, buffered, voltage-out-
put digital-to-analog converters (DAC A and DAC B) in a
small 8-pin SOT23 package. Both DAC outputs can
source and sink 1mA to within 100mV of ground and
VDD. The MAX5222 operates with a single +2.7V to
+5.5V supply.
The device uses a 3-wire serial interface, which oper-
ates at clock rates up to 25MHz and is compatible with
SPI, QSPI, and MICROWIRE interface standards.
The serial input shift register is 16 bits long and con-
sists of 8 bits of DAC input data and 8 bits for DAC
selection and shutdown control. DAC registers can be
loaded independently or in parallel at the positive edge
of CS.
The MAX5222’s ultra-low power consumption and tiny
8-pin SOT23 package make it ideal for portable and
battery-powered applications. Supply current is less
than 1mA and drops below 1A in shutdown mode. In
addition, the reference input is disconnected from the
REF pin during shutdown, further reducing the system’s
total power consumption.
