General Description
The TC1321 is a serially accessible, 10-bit voltage
output, digital-to-analog converter (DAC). The DAC
produces an output voltage that ranges from ground to
an externally supplied reference voltage. It operates
from a single 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 (POR) function
that ensures that the device starts at a known condition.
Communication with the TC1321 is accomplished via a
simple 2-wire SMBus/I2C compatible serial port, with
the TC1321 acting as a slave only device. The host can
enable the SHDN bit in the CONFIG register to activate
the Low Power Standby mode.
