Texas Instruments 6PAIC3104IRHBRQ1

The TLV320AIC3104-Q1 is a low-power stereo audio codec with stereo headphone amplifiers, as well as multiple inputs and outputs that are programmable in single-ended or fully differential configurations. Extensive register-based power control is included, enabling stereo 48-kHz DAC playback as low as 14 mW from a 3.3-V analog supply, making it ideal for car audio applications in cluster and head unit systems.

The record path of the TLV320AIC3104-Q1 contains integrated microphone bias, digitally controlled stereo microphone preamplifier, and automatic gain control (AGC), with mix/mux capability among the multiple analog inputs. Programmable filters are available during record which can remove audible noise that can occur during noisy and unpredictable environments, such as when an e-call system is activated. The playback path includes mix/mux capability from the stereo DAC and selected inputs, through programmable volume controls, to the various outputs.

The TLV320AIC3104-Q1 contains four high-power output drivers as well as two fully differential output drivers. The high-power output drivers are capable of driving a variety of load configurations, including up to four channels of single-ended 16-Ω headphones using AC-coupling capacitors, or stereo 16-Ω headphones in a capless output configuration. These parameters enable the TLV320AIC3104-Q1 to act as an interface between the MCU and speaker amplifiers, such as the TPA3111D1-Q1, in various audio applications in the infotainment and cluster fields.

The stereo audio DAC supports sampling rates from 8 kHz to 96 kHz and includes programmable digital filtering in the DAC path for 3D, bass, treble, midrange effects, speaker equalization, and de-emphasis for 32-kHz,
44.1-kHz, and 48-kHz sample rates. The stereo audio ADC supports sampling rates from 8 kHz to 96 kHz and is preceded by programmable gain amplifiers (PGA) or an automatic gain control (AGC) circuit that can provide up to 59.5-dB analog gain for low-level microphone inputs. The TLV320AIC3104-Q1 provides an extremely high range of programmability for both attack (8 ms to 1,408 ms) and for decay (0.05 s to 22.4 s). This extended AGC range allows the AGC to be tuned for many types of applications.

Where neither analog nor digital signal processing are required, the device can be put in a special analog signal passthrough mode. This mode significantly reduces power consumption, as most of the device is powered down during this passthrough operation.

The serial control bus supports the I2C protocol, whereas the serial audio data bus is programmable for I2S, left/right-justified, DSP, or TDM modes. A highly programmable PLL is included for flexible clock generation and support for all standard audio rates from a wide range of available MCLKs, varying from 512 kHz to 50 MHz, with special attention paid to the most-popular cases of 12-MHz, 13-MHz, 16-MHz, 19.2-MHz, and 19.68-MHz system clocks.

The TLV320AIC3104-Q1 operates from an analog supply of 2.7 V to 3.6 V, a digital core supply of 1.525 V to 1.95 V, and a digital I/O supply of 1.1 V to 3.6 V.
