MAX551/MAX552 19-1260 Rev 1 9/02 +3V/+5V, 12-Bit, Serial, Multiplying DACs in 10-Pin MAX Package General Description Features The MAX551/MAX552 are 12-bit, current-output, 4-quad- Single-Supply Operation: rant multiplying digital-to-analog converters (DACs). +4.5V to +5.25V (MAX551) These devices are capable of providing unipolar or +2.7V to +3.6V (MAX552) bipolar outputs when operating from either a single +5V 12.5MHz 3-Wire Serial Interface (MAX551) or +3V (MAX552) power supply. An internal power-on-reset circuit clears all DAC registers on SPI/QSPI and MICROWIRE Compatible power-up, setting the DAC output voltage to 0V. Power-On Reset Clears DAC Output to Zero The SPI/QSPI and MICROWIRE-compatible 3- Asynchronous Clear Input Clears DAC Output wire serial interface saves board space and reduces to Zero power dissipation compared with parallel-interface devices. The MAX551/MAX552 feature double-buffered Voltage Mode or Bipolar Mode Operation with interface logic with a 12-bit input register and a 12-bit a Single Power Supply DAC register. Data in the DAC register sets the DAC Schmitt-Trigger Digital Inputs for Direct output voltage. Data is loaded into the input register through the serial interface. The LOAD input transfers Optocoupler Interface data from the input register to the DAC register, updat- 0.4A Supply Current ing the DAC output voltage. 10-Pin MAX Package The MAX551/MAX552 are available in an 8-pin DIP package or a space-saving 10-pin MAX package. The MAX package provides an asynchronous clear (CLR) Ordering Information input that clears all DAC registers when pulled to GND, setting the output voltage to 0V.
