DESCRIPTION

1

DVDD

Supply

Digital supply.

2

NPD

Digital input

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

and all output stages. This pin is active low.

3

NLDAC

Digital input

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

latch from the holding latches.

4

DIN

Digital input

Serial data input.

5

SCLK

Digital input

Serial clock input.

6

NCS

Digital input

Chip select. This pin is active low.

7

FS

Digital input

Frame synchronisation for serial output data.

8

DGND

Ground

Digital ground.

9

AGND

Ground

Analogue ground.

10

REFINCD

Analogue input

Voltage reference input for DACs C and D.

11

OUTD

Analogue output

DAC D output.

12

OUTC

Analogue output

DAC C output.

13

OUTB

Analogue output

DAC B output.

14

OUTA

Analogue output

DAC A output.

15

REFINAB

Analogue input

Voltage reference input for DACs A and B.

16

AVDD

Supply

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.
