MAX552 - +3V/+5V / 12-Bit / Serial / Multiplying DACs

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.

Key Features

  • o Single-Supply Operation: +4.5V to +5.25V (MAX551) +2.7V to +3.6V (MAX552) o 12.5MHz 3-Wire Serial Interface o SPI/QSPI and Microwire Compatible o Power-On Reset Clears DAC Output to Zero o Asynchronous Clear Input Clears DAC Output to Zero o Voltage Mode or Bipolar Mode Operation with a Single Power Supply o Schmitt-Trigger Digital Inputs for Direct Optocoupler Interface o 0.4µA Supply Current o 10-Pin µMAX Package MAX551/MAX552 ______________Ordering Information PART MAX551ACPA MAX551BCPA M.

19-1260; Rev 0; 10/97 +3V/+5V, 12-Bit, Serial, Multiplying DACs in 10-Pin µMAX Package _______________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.
