SBASA91 December 2020 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 to configure 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 device can support multiple devices by sharing the common I2C and TDM buses across devices. Moreover, the device includes a daisy-chain feature and a secondary audio serial output data pin. 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.
