MAX551ACPA+

The MAX551ACPA+ is a 5V, 12bit, serial, multiplying digital to analogue converter (DAC) in 8 pin DIP package. This current-output, 4-quadrant multiplying DAC is capable of providing unipolar or bipolar outputs. 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. It features double buffered interface logic with a 12bit input register and a 12bit DAC register. Data in the DAC register sets the DAC output voltage. Data is loaded into the input register through the serial interface. It is used in automatic calibration, gain adjustment, transducer drivers, digitally controlled filters and programmable amplifiers/attenuators.
