Featuring ultra-low distortion, integrated click/pop suppression, and robust short circuit and thermal protection, it supports both analog and I2C digital volume control. Designed for easy integration with a slim, cool-running form factor, it’s ideal for portable and battery-powered audio projects. ## Description This 20W stereo amplifier is a slim board has a class D amplifier onboard that can drive 2 channels of 4-8 ohm impedance speakers at 20W each. Power it with 5-12VDC using the onboard DC power jack and plug stereo line level into the 3.5mm stereo headphone jack and jam out with ease. Since it's class D, its completely cool-running, no heat sinks are required and it's extremely efficient - up to 93% efficiency makes it great for portable or battery powered rigs.The MAX9744 amplifier is very easy to use and has both analog and digital volume control capability. Use a single 1KΩ pot (included) to adjust volume analog-style or hook it up to a microcontroller and send I2C commands to set 64-steps of volume amplification.The MAX9744 has been mounted into a breakout, with polarity-protection, jacks and terminal blocks, i2c level shifting, and a spot to solder in a volume potentiometer. Each order comes with one MAX9744 breakout board with all surface-mount parts fully assembled and d, 3 x 2pin and 1 x 3pin terminal blocks, a 470uF power filter capacitor and 1KΩ trim potentiometer.Note: To use this board, a little soldering is required to attach the terminal blocks and other components, but its fairly easy and expect it should take less than 15 minutes. Review: Habe die platine in den PAL Tivoli Audio eingebaut, ersetzt dort die duchgebrannte Endstufe. Keine Klangeinbußen feststellbar. Die Lötarbeiten waren simpel und sind bei Adafruit gut erklärt. Die kleine Platine ließ sich genau zwischen Lautsprecher und Batteriefach einschieben. Review: Simple, facile à mettre en oeuvre. Je l'ai relié à 2 haut parleurs de récupération. Fonctionne sans problème. ## Features - Power From 4.5V 14V Dc Voltage - Up To 93% Efficient (88 93% Typical) - 20Ma Quiescent Current (Or Put Into Shutdown For 1Ua Quiescent) - Up To 29.5Db Max n - Use Dc Or Ac Coupled Line Level Input, Up To 3Vpp.Filterless Spread Spectrum Modulation Lowers.20W Stereo Output (4&Amp;Omega;, Vdd 12V, Thd+N 10%).Low 0.04% Thd+N.Integrated Click And Pop Suppression.Short Circuit And Thermal Overload Protection ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00SK8OH30 | | Are Batteries Included | No | | Best Sellers Rank | #132,882 in Electronics ( See Top 100 in Electronics ) #394 in Home Audio Amplifiers | | Brand | Adafruit | | Customer Reviews | 4.2 4.2 out of 5 stars (56) | | Date First Available | 2 April 2016 | | Item Weight | 9.07 g | | Item model number | 1752 | | Manufacturer | Adafruit | | Product Dimensions | 4.1 x 5.4 x 0.2 cm; 9.07 g | | Voltage | 14 Volts | ## Product Details - **Battery capacity:** 8 - **Brand:** Adafruit - **Item dimensions L x W x H:** 41 x 54 x 2 millimeters - **Unit count:** 1 Count - **Voltage:** 14 Volts ## Images ![Stereo 20W Class D Audio Amplifier - MAX9744 - Image 1](https://m.media-amazon.com/images/I/71Lvp3S6KIL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by P***7 on 7 January 2020* Habe die platine in den PAL Tivoli Audio eingebaut, ersetzt dort die duchgebrannte Endstufe.

Je l'ai relié à 2 haut parleurs de récupération. Fonctionne sans problème. ### ⭐⭐⭐⭐⭐ Review *by N***N on 7 July 2016* Product delivered was exactly what was expected, and from Adafruit. Some assembly was needed but I found a fantastic guide from Adafruit that explained the whole thing. Works perfectly well, zero detectable noise when sitting idle, and this little board gets loud enough to comfortably fill a room! I have it in analog mode driving 2 40w bookshelf speakers and it performs from the lowest to the highest frequencies with no discernible distortion, even all the way up! Highly recommended if you can handle the assembly process, I was able to do it carefully within a half hour. ## Frequently Bought Together - Adafruit 1752 Development Board Accessories (Audio Amplifier, 41mm, 54mm, 2mm, 11g) - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - EDGELEC 120pcs Breadboard Jumper Wires 20cm Wire Length Optional Dupont Cable Assorted Kit Male to Female Male to Male Female to Female Multicolored Ribbon Cables --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.eg/products/330190724-stereo-20w-class-d-audio-amplifier-max9744](https://www.desertcart.com.eg/products/330190724-stereo-20w-class-d-audio-amplifier-max9744) --- *Product available on Desertcart Egypt* *Store origin: EG* *Last updated: 2026-05-05*
