TLV320AIC3109EVM

The TLV320AIC3109EVM showcases the latest Texas Instruments (TI) mono audio codec, the
TLV320AIC3109-Q1 (U3). The TLV320AIC3109-Q1 device is a low-power mono audio codec with a mono
headphone amplifier and multiple input and output channels that are programmable in single-ended or
fully differential configurations.

The EVM offers different test points, terminals and headers used to evaluate, test and configure the
TLV320AIC3109 audio codec in the board. The layout of the board separates analog and digital sections
all layers; the analog input and outputs, and analog power supply regulator are located in the left side of
the board, while the right side of the board has all the digital signals, like the I²C lines, digital audio signals
and onboard EEPROM. Ground planes for both analog and digital grounds are separated, but two
common connection points are available through headers J28 and J29. The EVM was designed following
the layout recommendations from

TLV320AIC3109-Q1 Automotive, Low-Power, 96-kHz, Mono Audio

. Several connectors at the edge of the board provide access to the different inputs and outputs of

the device. Options to evaluate special features, such as capless headphone configuration and internal
mic bias generation are also available. Power, digital audio data, and digital connection for the
configuration and control of the device is provided by the USB-MODEVM board. The
