DESCRIPTION
Analog voltage supply input
Positive reference voltage input
Negative reference voltage input
DAC amplifier sense input.
Analog output voltage from DAC
Ground.
Asynchronous input to clear the DAC registers. When CLR is low, the DAC register is set to 000h and the output
voltage to 0V.
Frame synchronization input. The falling edge of the SYNC pulse indicates the start of a serial data frame shifted out
to the DAC7551.
