_______________General Description

The MAX551/MAX552 are 12-bit, current-output, 4-quad­rant multiplying digital-to-analog converters (DACs).
These devices are capable of providing unipolar or
bipolar outputs when operating from either a single +5V
(MAX551) or +3V (MAX552) power supply. An internal
power-on-reset circuit clears all DAC registers on
power-up, setting the DAC output voltage to 0V.

The SPI™/QSPI™ and Microwire™-compatible 3-wire
serial interface saves board space and reduces power
dissipation compared with parallel-interface devices.
The MAX551/MAX552 feature double-buffered interface
logic with a 12-bit input register and a 12-bit DAC regis­ter. Data in the DAC register sets the DAC output volt­age. Data is loaded into the input register via the serial
interface. The LOAD input transfers data from the input
register to the DAC register, updating the DAC output
voltage.

The MAX551/MAX552 are available in an 8-pin DIP
package or a space-saving 10-pin µMAX package. The
µMAX package provides an asynchronous clear (CLR)
input that clears all DAC registers when pulled to GND,
setting the output voltage to 0V.

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.
