Typical Circuit Configuration
Figure 18. Typical Circuit Configuration
Application Overview
The TLV320AIC3253 offers a wide range of configuration options. Figure 1 shows the basic functional blocks of
the device.
Device Connections
Digital Pins
Only a small number of digital pins are dedicated to a single function; whenever possible, the digital pins have a
default function, and also can be reprogrammed to cover alternative functions for various applications.
The fixed-function pins are Reset and the SPI_Select pin, which are HW control pins. Depending on the state of
SPI_Select, the two control-bus pins SCL/SSZ and SDA/MOSI are configured for either I2C or SPI protocol.
Other digital IO pins can be configured for various functions via register control. An overview of available
functionality is given in Multifunction Pins.
Analog Pins
Analog functions can also be configured to a large degree. For minimum power consumption, analog blocks are
powered down by default. The blocks can be powered up with fine granularity according to the application needs.
