Signal
Description
Pin No.
Name
Type
10
ADCIN3
I/P
Analogue to digital converter input 3 (ADC3)
11
ADCIN4
I/P
Analogue to digital converter input 4 (ADC4)
12
VSS
POWER
The negative supply rail (ground) for both analogue and
digital supplies.
13
VBIAS
O/P
An analogue bias line for the internal circuitry, held at ½
AVDD. 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
AVDD
POWER
The positive analogue supply rail. Analogue levels and
voltages are dependent upon this supply. This pin should
be decoupled to VSS by a capacitor.
20
MOD1 IN
I/P
Input to MOD1 variable attenuator.
21
MOD2 IN
I/P
Input to MOD2 variable attenuator.
22
MOD1
O/P
Output of MOD1 variable attenuator.
23
MOD2
O/P
Output of MOD2 variable attenuator.
24
DVDD
POWER
The positive digital supply rail. Digital levels and voltages
are dependent upon this supply. This pin should be
decoupled to VSS by a capacitor.
