Part Number : MAX551AEPA
Function : +3V/+5V, 12-Bit, Serial, Multiplying DACs in 10-Pin µMAX Package
Manufacturers : Maxim Integrated
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 LOADinput transfers data from the input register to the DAC register, updating the DAC output voltage.
