11.1 Overview
The TLV320AIC3106 is a highly flexible, low power, stereo audio codec with extensive feature integration,
intended for applications in smartphones, PDAs, and portable computing, communication, and entertainment
applications. Available in a 5x5mm 80-ball BGA (with 51 balls actually used) and 7x7mm 48-lead QFN, the
product integrates a host of features to reduce cost, board space, and power consumption in space-constrained,
battery-powered, portable applications.
The TLV320AIC3106 consists of the following blocks:
• Stereo audio multi-bit delta-sigma DAC (8 kHz–96 kHz)
• Stereo audio multi-bit delta-sigma ADC (8 kHz–96 kHz)
• Programmable digital audio effects processing (3-D, bass, treble, mid-range, EQ, notch filter, de-emphasis)
• Six audio inputs
• Four high-power audio output drivers (headphone drive capability)
• Three fully differential line output drivers
• Fully programmable PLL
• Headphone/headset jack detection with interrupt
Communication to the TLV320AIC3106 for control is pin-selectable (using the SELECT pin) as either SPI or I²C.
The SPI interface requires that the Slave Select signal (MFP0) be driven low to communicate with the
TLV320AIC3106. Data is then shifted into or out of the TLV320AIC3106 under control of the host
microprocessor, which also provides the serial data clock. The I²C interface supports both standard and fast
communication modes, and also enables cascading of up to four multiple codecs on the same I²C bus through
the use of two pins for addressing (MFP0, MFP1).
