Description
- 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.
