_______________General Desc ription
The MAX522 contains two 8-bit, buffered, voltage-output
digital-to-analog converters (DAC A and DAC B) in small
8-pin SO and DIP packages. DAC A’s buffer can source
and sink 5mA, and DAC B’s output can source and sink
500μA, both to within 0.5V of ground and V
DD
. The
MAX522 operates with a single +2.7V to +5.5V supply.
The device utilizes a 3-wire serial interface, which oper-
ates at clock rates up to 5MHz and is compatible with
SPI , QSPI , and Microwire interface standards.
The serial input shift register is 16 bits long and con-
sists of eight bits of DAC input data and eight bits for
DAC selection and shutdown control. DAC registers
can be loaded independently or in parallel at the posi-
tive edge of CS.
The MAX522’s ultra-low power consumption and small
8-pin SO package make it ideal for portable and bat-
tery-powered applications. Supply current is less than
1mA and drops below 1μA in shutdown mode. In addi-
tion, the reference input is disconnected from the REF
pin during shutdown, further reducing the system’s total
power consumption. The software format is compatible
with the MAX512/MAX513 triple 8-bit DACs.
