SBASA91A December 2020 – June 2021 TLV320ADC3120
The TLV320ADC3120 is a high-performance, low-power, flexible, 2-channel, audio analog-to-digital converter (ADC) with extensive feature integration. This device is intended for applications in voice-activated systems, professional microphones, audio conferencing, portable computing, communication, and entertainment applications. The high dynamic range of the device enables far-field audio recording with high fidelity. This device integrates a host of features that reduces cost, board space, and power consumption in space-constrained, battery-powered, consumer, home, and industrial applications.
The TLV320ADC3120 consists of the following blocks:
Communication to the TLV320ADC3120 for configuring the control registers is supported using an I2C interface. The device supports a highly flexible audio serial interface [time-division multiplexing (TDM), I2S, or left-justified (LJ)] to transmit audio data seamlessly in the system across devices.
The TLV320ADC3120 can support multiple devices by sharing the common TDM bus across devices. Moreover, the device includes a daisy-chain feature as well. These features relax the shared TDM bus timing requirements and board design complexities when operating multiple devices for applications requiring high audio data bandwidth.
Table 8-1 lists the reference abbreviations used throughout this document to registers that control the device.
