General Description
The TC1320 is a serially accessible 8-bit voltage output
digital-to-analog converter (DAC). The DAC produces
an output voltage that ranges from ground to an exter-
nally supplied reference voltage. It operates from a sin-
gle power supply that can range from 2.7V to 5.5V,
making it ideal for a wide range of applications. Built
into the part is a Power-on Reset function that ensures
that the device starts at a known condition.
Communication with the TC1320 is accomplished via a
simple 2-wire SMBus/I2C™ compatible serial port with
the TC1320 acting as a slave only device. The host can
enable the SHDN bit in the CONFIG register to activate
the Low Power Standby mode.

Description
Input. Voltage Reference Input can range from 0V to 1.2V below VDD.
Bi-directional. Serial data is transferred on the SMBus in both directions
using this pin.
Input. SMBus serial clock. Clocks data into and out of the TC1320.
Ground.
Output. Buffered DAC output voltage. This voltage is a function of the
reference voltage and the contents of the DATA register.
No connection.
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.
Positive power supply input. See electrical specifications.
