OWER
The negative supply rail (ground) for both analogue and
digital supplies.
13
V
BIAS
O/P
An analogue bias line for the internal circuitry, held at
AV
DD
. This pin must be decoupled by a capacitor mounted
close to the device pins.
14
N/C
No internal connection. Do not make any connection to
this pin.
15
DACOUT1
O/P
Digital to analogue converter No. 1 output (DAC1)
16
DACOUT2
O/P
Digital to analogue converter No. 2 output (DAC2)
17
DACOUT3
O/P
Digital to analogue converter No. 3 output (DAC3)
18
N/C
No internal connection. Do not make any connection to
this pin.
19
AV
DD
P
OWER
The positive analogue supply rail. Analogue levels and
voltages are dependent upon this supply. This pin should
be decoupled to V
SS
by a capacitor.
20

O/P
Output of MOD2 variable attenuator.
24
DV
DD
P
OWER
The positive digital supply rail. Digital levels and voltages
are dependent upon this supply. This pin should be
decoupled to V
SS
by a capacitor.
