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.

Features

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