DESCRIPTION
NAME
NO.
I/O
DESCRIPTION
AGND
5
Analog ground. AGND is the reference and return terminal for the analog signals and supply.
A0, A1
17, 16
I
DAC select inputs. The combination of high or low levels select either DACA, DACB, DACC, or DACD.
DGND
6
Digital ground. DGND is the reference and return terminal for the digital signals and supply.
DB0 – DB7
14–7
I
Digital DAC data inputs. DB0 – DB7 are the input digital data used for conversion.
OUTA
2
O
DACA output. OUTA is the analog output of DACA.
OUTB
1
O
DACB output. OUTB is the analog output of DACB.
OUTC
20
O
DACC output. OUTC is the analog output of DACC.
OUTD
19
O
DACD output. OUTD is the analog output of DACD.
REF
4
I
Voltage reference input. The voltage level on REF determines the full scale analog output.
VDD
18
Positive supply voltage input terminal
VSS
3
Negative supply voltage input terminal
WR
15
I
Write input. WR selects DAC transparency or latch mode. The selected input latch is transparent when WR
is low.
Terminal numbers shown are for the DW and N packages.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
The VSS terminal is connected to the substrate and must be tied to the most negative supply voltage applied to the device.
NOTES:
1. Output voltages may be shorted to AGND provided that the power dissipation of the package is not exceeded. Typically short circuit
current to AGND is 60 mA.
2. For operation above TA = 75°C, derate linearly at the rate of 2 mW/°C.
