TC1320 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
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 TC1320. 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 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. 8 VDD Power Positive power supply input. See electrical specifications. 2002-2012 Microchip Technology Inc. DS21386C-page 5
