PIN DESCRIPTIONS
The descriptions of the pins are listed in Table 2-1.
TABLE 2-1:
PIN FUNCTION TABLE
Pin Number
Symbol
Type
Description
1
VREF
Input
Input. Voltage Reference Input can range from 0V to 1.2V below VDD.
2
SDA
Bi-Directional
Bi-directional. Serial data is transferred on the SMBus in both directions
using this pin.
3
SCL
Input
Input. SMBus serial clock. Clocks data into and out of the TC1322.
4
GND
Power
Ground.
5
VOUT
Output
Output. Buffered DAC output voltage. This voltage is a function of the
reference voltage and the contents of the DATA register.
6
NC
None
No connection.
7
DAC-OUT
Output
Output. Unbuffered DAC output voltage. This voltage is a function of the ref-
erence voltage and the contents of the DATA register. This output is
unbuffered and care must be taken that the pin is connected only to a
high-impedance node.
8
VDD
Power
Input. Positive power supply input. See electrical specifications.
