The TLV320AIC13IDBTR is a high-performance, low-power stereo audio codec with integrated class-D speaker amplifiers by Texas Instruments. It is a single chip solution with flexible design features, making it ideal for audio applications such as Bluetooth speakers, portable audio and other audio solutions requiring extended battery life. The TLV320AIC13IDBTR combines a low-power audio CODEC with class-D audio amplifiers, microphone preamplifier and multi-function analog audio I/O. The device is designed to minimize board space, reduce external components and minimize power consumption.

The TLV320AIC13IDBTR integrates two class-D speaker amplifiers each capable of delivering up to 2W of output power into a 4Ω load. The amplifier is designed for low electromagnetic interference (EMI) and to minimize power consumption. Both amplifiers feature differential outputs and are independently controlled by the main CODEC. The device also provides a single-ended or differential microphone preamplifier to interface directly with most single-ended and differential microphones. The preamplifier includes automatic gain control with selectable attack and release times. The device also includes an internally-controlled analog mixer to mix audio received from the CODEC and microphone inputs.

The TLV320AIC13IDBTR includes an audio Analog-to-Digital Converter (ADC) and a Digital-to-Analog Converter (DAC). The ADC features 24-bit accuracy and up to 96kHz sample rate. The DAC is optimized for minimum THD+N and features a 32-bit architecture to ensure good signal-to-noise ratio. Both the ADC and DAC support stereo audio. The device also provides digital audio interfaces for I2S and DSP formats, support for master or slave modes for both synchronous and asynchronous data transfers.

The TLV320AIC13IDBTR also integrates several useful features, including programmable gain, pop filter and DC offsets. The programmable gain feature allows for adjustment of the output power level, allowing for a wide variety of output power levels to match the application. Pop filter reduces acoustic resonance during power-up and power-down of the device, while DC offsets provide dc blocking and act as a safeguard against over-current situations.

In addition, the TLV320AIC13IDBTR also includes a differential output headphone amplifier with programmable gain control. This amplifier is protected against RF interference and has a low-impedance output to drive stereo headphones. The device also includes a programmable reference clock, a digital signal processing (DSP) processor and an advanced power manager to reduce power consumption.

The TLV320AIC13IDBTR is an ideal device for applications such as portable audio and Bluetooth speakers. It provides a comprehensive audio signal interface and integrates many useful features to maximize battery life and to minimize 10 board space. The device is designed to work on a wide range of supply voltages from 1.8V to 3.3V and supports both I2S and DSP audio interfaces. Its flexible design makes it well-suited for a wide range of audio applications.
