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/I
2
C鈩?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.
