Pin Number
Symbol
Type
Description
1VREF
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 TC1321.
4
GND
Power
Ground.
5VOUT
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
reference 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.
8VDD
Power
Positive power supply input. See electrical specifications.
