TLV320AIC20KIPFBR

The TLV320AIC20KIPFBR is a low‑power, dual‑channel, audio codec with integrated filters. It is designed for use in portable applications, specifically those involving wearable devices. The codec is based on a high‑performance, highly integrated architecture with a low‑power consumption profile. The TLV320AIC20KIPFBR features a low power/high performance architecture, an integrated headphone amplifier, and a flexible audio interface with support for up to 16‑bit, 48 kHz sample rate audio.

The TLV320AIC20KIPFBR interfaces directly with the Application Processor (AP) and the Analog‑to‑Digital or Digital‑to‑Analog converter. It uses a single I2C or S‑BUS protocol for control and commands. The TLV320AIC20KIPFBR provides complete audio system level integration including line inputs, stereo mic inputs and outputs, a headphone amp (with optional stereo gain control), sample rate converters, clocking support, digital mic support and advanced audio routing.

TLV320AIC20KIPFBR’s application field and applications include:

• Smartphones
• Tablets
• Wearables
• Headsets
• Speakers
• Video Conferencing Units
• Video Game Consoles
• Portable Media Players
• Home Entertainment Systems
• Robotics

The TLV320AIC20KIPFBR’s architecture is designed to reduce power consumption and overall system cost. It is capable of operating in either a master or a slave mode. In master mode, the TLV320AIC20KIPFBR controls the ADCs and DACs and handles the audio routing within the system. When working in slave mode, the codec is driven by an external master, such as a DSP or processor.

The codec is capable of handling both mono and stereo audio streams and providing flexible audio routing. It integrates a headphone amplifier with stereo gain control. The amplifier can drive up to 32 ohms of impedance. The headphone amplifier also features adjustable THD+N and supports various audio modes such as Virtual Bass, Virtual Surround (VSR) and Stereo Enhance. The codec also supports programmable microphone bias voltage, MDAC (mini digital audio controllers) and mono and stereo sample rate conversion.

The TLV320AIC20KIPFBR also supports built-in digital microphone support. It is capable of interfacing up to eight digital microphones. It also supports two analog input and two analog output channels. The TLV320AIC20KIPFBR has I²S support and works at both 16- and 32-bit data resolutions. It also supports a range of sample rates up to 48 kHz.

The TLV320AIC20KIPFBR is a low power, high performance, audio codec with built-in microphone support and flexible audio routing capabilities. It offers a low power profile and a highly integrated architecture suited for various portable applications, including those involving wearable devices. With its low power consumption, optimized audio performance and flexible audio routing, the TLV320AIC20KIPFBR is an ideal choice for a wide range of applications.
