Max9724

The MAX9724 is a high-performance, 60mW DirectDrive stereo headphone amplifier from Analog Devices (formerly Maxim Integrated), widely used in portable electronics for its space-saving architecture and superior RF noise rejection FarnellAnalog.

1. Product Overview & Key Features

The core innovation of the MAX9724 is its DirectDrive technology, which uses an internal charge pump to generate a negative rail, allowing a ground-referenced output without the need for large, bulky DC-blocking capacitors AnalogAnalog.

* Audio Quality: Low THD+N (0.02%) and integrated click-and-pop suppression ensure clean audio transitions Analog.

* RF Immunity: Specifically designed to reject RF interference (up to 67dB better than standard amps), making it ideal for smartphones and wireless devices Analog.

* Power Efficiency: Operates on a single 2.7V to 5.5V supply with a low 3.5mA quiescent current and a <0.1µA shutdown mode Analog.

2. Market Trends & Insights (2025-2026)

The market for audio amplifiers like the MAX9724 is driven by the continued miniaturization of consumer electronics and the rising demand for high-fidelity portable audio.

* Market Growth: The global audio amplifier market is projected to grow from $4.57 billion in 2025 to $5.99 billion by 2026, driven by smart home and portable device adoption YahooMordorintelligence.

* Miniaturization: There is a strong shift toward ultra-compact packages like the 1.5mm x 2mm UCSP used by the MAX9724, as board space remains a premium in wearables and high-end smartphones Analog.

* Competitive Landscape: While the MAX9724 remains a staple, it faces stiff competition from Texas Instruments' TPA6132A2, which offers higher PSRR (100dB) and fully differential inputs for better noise rejection in dense digital systems Ti.

3. B2B Sourcing Data

Current B2B market data shows active availability for the MAX9724 series, particularly from suppliers in Shenzhen and Hong Kong.

* Pricing: Bulk pricing typically ranges from $0.19 to $2.88 per unit, depending on the specific variant (A/B/C/D) and order volume.

* MOQ: Minimum order quantities vary significantly, from as low as 5-10 pieces for sample batches to 2,500 pieces for wholesale factory reels.
