MAX9830 is a mono 2W D-class amplifier from MAXIM, which provides AB-class audio performance and D-class efficiency. It uses active edge rate and overshoot control circuitry to greatly reduce EMI. The filterless spread-spectrum modulation scheme eliminates the need for output filtering found in traditional D-class devices. These features reduce application component count. MAX9830's industry-leading 1.6mA at 5V, 1.2mA at 3.6V, quiescent current extends battery life in portable applications. MAX9830 is available in an 8-pin TDFN (2mm x 2mm x 0.8mm) and is specified over the extended -40°C to +85°C temperature range.

The MAX9744 is a 20W stereo Class D audio power amplifier that provides Class AB amplifier performance with Class D efficiency. It features single-supply operation, adjustable gain, shutdown mode, a SYNC output, speaker mute, and industry-leading click-and-pop suppression. The MAX9744 features a 64-step dual-mode (analog or digital), programmable volume control and mute function. It operates from a 4.5V to 14V single supply and can deliver up to 20W per channel into a 4Ω speaker with a 14V supply. The MAX9744 offers two modulation schemes: a fixed-frequency modulation mode that allows one of several preset switching frequencies to be selected, and a spread-spectrum modulation mode that helps to reduce EMI-radiated emissions. The MAX9744 features high 75dB PSRR, low 0.04% THD+N, and SNR in excess of 90dB. Robust short-circuit and thermal-overload protection prevent device damage during a fault condition.

MAX9736A/B/D is a high-performance, high-efficiency Class D amplifier that can operate from 8V to 28V and provide up to 88% efficiency.

The MAX9768 mono 10W Class D speaker amplifier provides high-quality, efficient audio power with an integrated volume control function. The MAX9768 features a 64-step dual-mode (analog or digitally programmable) volume control and mute function.

The MAX9742 is a 16W, Class D stereo amplifier from MAXIM that operates from a single or dual supply. The maximum output power is 2 x 16W into a 4Ω load and the input impedance is fully differential. The MAX9742 features a variety of protection functions, including short-circuit and thermal overload protection. It is also available in a space-saving 36-pin TQFN package.

The MAX9741 stereo Class D audio power amplifier provides Class AB amplifier performance with Class D efficiency, conserving board space and eliminating the need for a bulky heatsink. Using a high-efficiency Class D architecture, it delivers 12W continuous output power into 8Ω loads. Proprietary modulation and switching schemes render the traditional Class D EMI suppression output filter unnecessary. The MAX9741 offers two modulation schemes: a fixed-frequency mode (FFM), and a spread-spectrum mode (SSM) that reduces EMI-radiated emissions. The device utilizes a fully differential architecture, a full bridged output, and offers comprehensive click-and-pop suppression. The MAX9741 features high 80dB PSRR, low 0.1% THD+N, and SNR in excess of 100dB. Short-circuit and thermal-overload protection prevent the device from being damaged during a fault condition.

The MAX9701 stereo Class D audio power amplifier provides Class AB amplifier audio performance with the benefits of Class D efficiency, eliminating the need for a heatsink while extending battery life. The MAX9701 delivers up to 1.3W per channel into an 8Ω load while offering 87% efficiency. Maxim’s next-generation, low-EMI modulation scheme allows the amplifier to operate without an external LC filter while still meeting FCC EMI emission levels. The MAX9701 offers two modulation schemes: a fixed-frequency (FFM) mode, and a spread-spectrum (SSM) mode that reduces EMI-radiated emissions. The MAX9701 oscillator can be synchronized to an external clock through the SYNC input, allowing synchronization of multiple Maxim Class D amplifiers. The sync output (SYNC_OUT) can be used for a master-slave application where more channels are required. The MAX9701 features a fully differential architecture, a full bridge-tied load (BTL) output, and comprehensive click-and-pop suppression. The device features internally set gains of 0dB, 6dB, 12dB, and 18dB selected through two gain-select inputs, further reducing external component count. The MAX9701 features high 80dB PSRR, less than 0.1% THD+N, and SNR in excess of 88dB. Short-circuit and thermal-overload protection prevent the device from being damaged during a fault condition. The MAX9701 is available in 24-pin thin QFN-EP (4mm x 4mm x 0.8mm) and 20-bump UCSP™ (2mm x 2.5mm x 0.6mm) packages.
