Twelve Parallel Input Data Bits. D11 = MSB Pin 18, D0 = LSB Pin 7, AD7396.
Ten Parallel Input Data Bits. D9 = MSB Pin 18, D0 = LSB Pin 9, AD7397 Only.
DAC A Voltage Output.
Analog Ground.
Digital Ground.
Load DAC A Register Strobe. Transfers input register data to the DAC A register. Active
low inputs, Level sensitive latch. May be connected together with LDB to double-buffer load
both DAC registers simultaneously.
Power Shutdown Active Low Input. DAC register contents are saved as long as power stays
on the V
Resets Input and DAC Register to Zero Condition. Asynchronous active low input.
No Connect Pins 7 and 8 On the AD7397 Only.
Chip Select Latch Enable, Active Low.
DAC Input Register Address Select DACA = 1 or DACB = 0.
Load DAC B Register Strobe. Transfers input register data to the DAC B register. Active low
inputs, Level sensitive latch. May be connected together with LDA to double-buffer load
both DAC registers simultaneously.
Positive Power Supply Input. Specified range of operation +2.7 V to +5.5 V.
DAC Reference Input Pin. Establishes DAC full-scale voltage.
DAC B Voltage Output.
