TLV320AIC20CPFB

Introduction

The TLV320AIC20CPFB is a low-power, mono CODEC that operates at levels suitable for microcontroller, DSP and specialized audio applications. The device features a multi-level interface and high level of integration including analog-to-digital sampling, digital-to-analog reconstruction and stereo headphone/headset stages all in a very compact package. The device is intended for use in applications such as portable and handheld products, voice-enabled wireless communications, audio toys and gaming, and feature telephone systems for use in home or automotive applications.

Application Field

The TLV320AIC20CPFB can be used in many different applications. It is used in portable and handheld audio products such as MP3 players, digital recorders, audio toys, voice-enabled wireless communications, gaming systems and home and automotive entertainment systems. It is also used in multimedia and internet-based systems, multimedia terminals, professional audio/video playback/editing, mobile and handheld phones and devices, and digital cameras.

Features

The TLV320AIC20CPFB is a low-power, mono CODEC featuring a multi-level interface and high level of integration including analog-to-digital sampling, digital-to-analog reconstruction and stereo headphone/headset stages. It supports up to 48 kHz sampling rates in single-ended and low-noise, high-frequency (100 kHz) differential voltage output. The device also includes a stereo headphone/headset amplifier stage, a PCM software-controlled microphone bias, audio input/output sliders, and a loopback between analog/digital interfaces. It is available in a very compact 8-pin UQFN package.

Working Principle

The TLV320AIC20CPFB uses an advanced signal processing and digital signal processing technique known as Direct Digital Synthesis (DDS). DDS is a method of generating digital signals from analog, or from an array of digital inputs. It converts a digital input stream into a digital signal, which is eventually converted back into analog form for transmission over a medium. DDS is used in a variety of applications such as D/A converters, signal generators, frequency synthesizers, digital reverberation, phase-locked loops, delay line filters and phase-shifters.
