Datasheet
The MAX551/MAX552 are 12-bit, current-output, 4-quad-
rant 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
through the serial interface. The LOAD input transfers
data from the input register to the DAC register, updat-
ing 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.
