The MAX989EUA+ is a stereo, differential output, Class D amplifier designed for mobile applications with low supply voltage operation and power efficiency. This device is part of Maxim\'s Linear-Comparators product family, and is designed for superior audio performance in mobile devices. The amplifier core is powered by a split-supply operating from 1.1 V to 2.7 V, making the MAX989EUA+ an ideal device for portable applications.
The MAX989EUA+ is optimized for high efficiency, low power consumption, and low distortion when operated from 1.1 V to 2.7 V. This device enables increased output current capability of up to 250 mA, which provides superior audio performance when compared to traditional Class AB amplifiers. Additionally, the efficiency of the amplifier allows mobile applications to extend battery life.
The MAX989EUA+ features a low power shutdown mode that reduces quiescent current to 50 μA, thereby enabling longer battery life.The device also features a side-tone feature that allows the microphone signal to be mixed into the amplifier output. The unique side-tone feature improves the audio quality by decreasing feedback distortion due to the added side-tone. Additionally, the device has a click-and-pop suppression circuit that eliminates popping noises when the CLASS D amplifier is powered up or down.
The MAX989EUA+ features selectable gain configuration from 6 dB to 16 dB. Additionally, it features an adjustable high-pass filter and adjustable low-pass filter that provide selectable corner frequencies from 10 kHz to 330 kHz. It also features a small-signal output swing to ground of up to ±200 mV. This device is available in a 16-pin 4 mm x 4 mm quad flat no-lead (QFN) package.
The MAX989EUA+ incorporates patented Stereo Current-Feedback Architecture (CFA) that provides superior audio performance in mobile applications. The device utilizes a differential output configuration and a fixed gain amplifier to minimize differential audio distortion. It produces very low overall distortion and delivers good dynamic range with both low and high output levels.
The device also features an integrated high-current power stage that drives an 8 ohm load up to 150 mA. The high-current power stage reduces thermal dissipation and improves power efficiency. The power stage is capable of driving up to 4 ohm loads with up to 200 mA of continuous output current.
In addition, the MAX989EUA+ is designed to work efficiently in mobile applications by incorporating advanced device features such as a wide supply voltage range, low noise performance, and low power supply current. The device has a built-in protection circuit that shuts down the output stage when the output voltage exceeds the set voltage limit. It is capable of operating at up to 85°C junction temperature.
Overall, the MAX989EUA+ is an efficient and reliable stereo, differential output, Class D amplifier designed for superior audio performance in mobile applications. This device is capable of providing a high-current output stage while reducing thermal dissipation and improving power efficiency. It is suitable for a variety of applications such as portable speakers, headphones, and portable media players.
