This document describes a filterless high efficiency mono 1.4W class-D audio amplifier with built-in output stage. The amplifier provides 1.4W into 8Ω speaker at 5.0V supply with less than 1% THD and achieves 85% efficiency. It has a signal-to-noise ratio better than 98dB and operates on a single supply from 2.5V to 5.0V. The amplifier features ultralow shutdown current of 20nA and provides short-circuit and thermal protection. It is suitable for applications such as mobile phones, MP3 players, portable gaming devices, and educational toys.

SSM2275 and SSM2475 are dual and quad rail-to-rail output audio amplifiers that achieve lower production costs than the industry standard OP275 (the first Butler Amplifier offered by Analog Devices). This lower cost amplifier also offers operation from a single 5 V supply, in addition to conventional ±15 V supplies. The ac performance meets the needs of the most demanding audio applications, with 8 MHz bandwidth, 12 V/µs slew rate and extremely low distortion. The SSM2275 and SSM2475 are ideal for application in high performance audio amplifiers as well as advanced analog/digital converters and analog/mixed signal applications.

This document describes the features and characteristics of Analog Devices' Mono 1.5 W/Stereo 250 mW Power Amplifier SSM2250 Rev. A. The amplifier is designed for desktop computers, sound cards, communication headsets, and other applications. It features mono 1.5 W differential or stereo 250 mW output, single-supply operation, low power shutdown current, low distortion, wide bandwidth, and is unity-gain stable.

The SSM2250 is a low-power monophonic or stereo power amplifier from Analog Devices, with 1.5 W of output power and 0.2% distortion, suitable for desktop computers, sound cards, headphones, handheld game consoles, etc.

This document provides a detailed introduction to SSM2211 audio amplifier, including product features, application scenarios, functions and usage methods.

The SSM2211 is a high-performance audio amplifier that delivers 1 W RMS of low-distortion audio power into a bridge-connected 8 Ω speaker load, (or 1.5 W RMS into a 4 Ω load). It operates over a wide temperature range and is specified for single-supply voltages between 2.7 V and 5.5 V. When operating from batteries, it will continue to operate down to 1.75 V, making the SSM2211 the best choice for unregulated portable computers, personal wireless communicators, hands-free telephones, speakerphones, intercoms, musical toys and speaking games.

This product is SSM2166 microphone preamplifier with variable compression and noise gating function. Main features include: single 14-lead package, single 5V power supply, adjustable noise gate threshold, adjustable compression ratio, automatic limiting function, low noise and distortion, low cost, 20kHz bandwidth, etc.

The SSM2165 is a complete and flexible solution for conditioning microphone inputs in computer audio systems. It is also excellent for improving vocal clarity in communications and public address systems. A low-cost, high-performance microphone preamplifier/processor with noise gate, limiter, and compression.

The SSM2164 is a low cost quad voltage controlled amplifier (VCA) with 100 dB dynamic range and 0.02% THD providing excellent value for cost sensitive gain control applications.

This document introduces the SSM2163 digital controlled 8 channel 2 channel audio mixer, including its features and characteristics, such as input and output, signal to noise ratio, distortion, applications, etc.

This document introduces Analog Devices' SSM2160/SSM2161, a 6-channel/4-channel serial input master/balance volume control. The product features clickless digitally controlled level adjustment, 128 levels of attenuation, 32 levels of gain, automatic power on mute, etc.
