2.0 PIN DESCRIPTIONS
The descriptions of the pins are listed in Table 2-1.
TABLE 2-1: PIN FUNCTION TABLE
Pin Number Symbol Type Description
1V
REF
Input Input. Voltage Reference Input can range from 0V to 1.2V below V
DD
.
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 TC1320.
4 GND Power Ground.
5V
OUT
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.
8V
DD
Power Positive power supply input. See electrical specifications.
