DESCRIPTION

Digital supply.

Power down. Powers down all DACs overriding their individual power down settings

and all output stages. This pin is active low.

Load DAC. Digital input active low. NLDAC must be taken low to update the DAC

latch from the holding latches.

Serial data input.

Serial clock input.

Chip select. This pin is active low.

Frame synchronisation for serial output data.

Digital ground.

Analogue ground.

Voltage reference input for DACs C and D.

DAC D output.

DAC C output.

DAC B output.

DAC A output.

Voltage reference input for DACs A and B.

Analogue supply.

ABSOLUTE MAXIMUM RATINGS

Absolute Maximum Ratings are stress ratings only. Permanent damage to the device may be caused by continuously operating at or

beyond these limits. Device functional operating limits and guaranteed performance specifications are given under Electrical

Characteristics at the test conditions specified

ESD Sensitive Device. This device is manufactured on a CMOS process. It is therefore generically susceptible to

damage from excessive static voltages. Proper ESD precautions must be taken during handling and storage of this

device.
