Audio A/D Converters

Analog Devices offers audio analog-to-digital converters (ADCs) for applications such as automotive, home theater, consumer audio, and PCs. These ADCs offer cost effective solutions and easy interfacing to ADI's SHARC® processor, Blackfin® processor, and SigmaDSP™ products.

Audio Amplifiers

Our audio amplifiers deliver audiophile performance with proven analog and digital technology. Analog Devices offers a wide range of audio products, including industry-leading microphone preamps, microphone drivers, line drivers, and receivers. ADI’s audio amplifier products also include Class-A, Class-B, and Class-D offerings, along with a breadth of power ICs. Our Class-D amplifiers are among the lowest power and lowest distortion in the industry. Analog Devices amplifier products have been used in many high volume consumer products where the highest audio quality is expected. The lowest power consumption also enables this performance in many battery powered applications as well. The deep technical knowledge of our experts on audio amplifiers is also available to help you fine tune your design to meet your specifications.

Audio CODECs

Analog Devices audio codecs feature extended temperature range, low noise and distortion, and easy multichannel interfacing to common DSPs, such as SHARC^® and SigmaDSP^®, and bring high fidelity to any audio signal chain. When combined with our DSP products and our SigmaStudio^® software, audio engineers can craft world-class audio experiences with a minimum of programming skills. ADI has audio codecs for many different applications, such as automotive, home theater, consumer audio, and PCs, and they are also widely used in systems such as automotive infotainment and road noise cancellation. Many soundbars use our audio codecs to enhance the sound to give you the best home theater experience.

Audio D/A Converters

Analog Devices offers a broad range of audio DACs for a number of applications. With a wide range of performance available, these audio DACs are perfectly suited for applications such as automotive audio, DVD players and recorders, audio video receivers, professional mixing consoles, and digital effects boxes.

Audio Jack Detectors

Analog Devices’ family of audio jack detectors provides a universal jack interface solution, as well as a compact solution for the power management and interface control of a powered accessory, such as an active noise cancelling (ANC) headset.

Audio Routing (Unbuffered)

Analog Devices offers a wide range of solutions for unbuffered routing of audio signals, including analog audio switches, multiplexers, and crosspoint switch matrices. Our unbuffered audio analog switches and multiplexers include single- and double-throw, single- and multichannel, serial and parallel interface, and programmable switches with low on resistance, low crosstalk, and clickless operation. Our serially controlled analog crosspoint switches feature dual or triple crosspoint matrix, 2-wire or 3-wire serial interface, and programmable operation with low crosstalk and clickless performance. Our audio switches and muxes are ideal for use in a variety of multimedia applications.

Audio Signal Processors

Analog Devices SigmaDSP® allows designers to use the SigmaStudio™ graphical tool with an audio digital signal processor without assembly or C coding. Many SigmaDSP processors also integrate high performance audio ADCs and DACs to build a full audio system on chip. ADI’s SHARC® processors are the leaders in quality audio processing and the Blackfin® processors lead in mobile multimedia.

Click-Pop Suppressors

Analog Devices provides integrated audio click-and-pop suppressors for devices, such as codecs that have integrated headphone amplifiers but lack a clickless and/or popless startup or shutdown. Our integrated click-pop suppression device control the ramping of the DC bias voltage on the output-coupling capacitors and the application of the audio signal to ensure that no audible transients are present at the headphones. Our audio click-and-pop suppressors help eliminate clicks and pops for a variety of applications such as portable multimedia devices, headphones, and audio line outputs.

Volume Control Devices

Analog Devices’ audio digital potentiometers provide stereo volume/balance control to replace mechanical potentiometers in audio applications requiring digitally controlled resistors. Wiper position can be controlled through a serial interface, debounced rotary encoder or push-button up/down interface. Features include single or dual potentiometers with log taper and up to 64 taps, up to 45 kΩ end-to-end resistance, stereo volume control, daisy-chaining, and clickless switching. Our volume control devices consume very little power while providing digital accuracy and reliability under flexible, automatic processor control.
