♦ Operates from a Single +2.7V to +5.5V Supply

♦ Dual Buffered Voltage Output

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

♦ Low Power Consumption:

1mA Operating Current

<1µA Shutdown Current

500µA, both to within 0.5V of ground and V . 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.

♦ Independently Programmable Shutdown Mode

♦ 5MHz, 3-Wire Serial Interface

♦ SPI™, QSPI™, and Microwire™ Compatible

♦ Space-Saving 8-Pin SO Package

______________Ord e rin g In fo rm a t io n

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.
