MAX9879ERV+T is a low-power audio amplifier with high output performance and low power consumption. It is designed for applications such as audio system power amplifiers, portable audio systems, automotive audio systems, and battery-operated systems. It offers superior sound quality with low power consumption in a tiny package.The MAX9879ERV+T is a high-efficiency linear amplifier that integrates enhanced circuitry with EMI suppression and power-down modes. It supports a wide range of supply voltages and is capable of driving loads up to 4V/4ohm and delivering up to 1W of continuous output. It also includes low- and high-power shutdown setpoints and three modes of EMI mitigation: slew-rate-control, frequency-notch-filter, and line-frequency-snubbing.The MAX9879ERV+T features a bridge amplification topology that facilitates high-power output levels while avoiding ground-bounce issues. The amplifier exhibits low distortion and low noise figures, as well as high power efficiency and wide dynamic range. The power output capability is highly optimized in the small package size. This feature enables the amplifier to achieve superior sound quality even at high power levels.The MAX9879ERV+T is designed to minimize power fade at medium to high output levels. Its patented dynamic power control algorithm actively adjusts the gain and power of the amplifier in response to sudden changes in the input signal level. This adjustment helps to reduce power wastage at normal operating levels.The MAX9879ERV+T also includes a low-power shutdown and high-power shutdown setpoints, which help to reduce overall power consumption. The low-power shutdown setpoint is adjustable, and the high-power shutdown setpoint can be activated with an external signal. These setpoints help to minimize power loss at low and full power levels.The MAX9879ERV+T also includes a high-dropout linear regulator and a low-noise digital power supply regulator. The built-in regulator provides stable power supply and helps to maintain linearity and minimize distortion. The low-noise digital power supply regulator helps to minimize switching noise when the amplifier is operating in low-power modes.The MAX9879ERV+T is designed to provide superior performance and reliability in various applications and environments. It is ideal for applications such as audio system power amplifiers and portable audio systems. Its low power consumption and small package size make it ideal for automotive and battery-operated systems. The high-efficiency, low-noise performance, and high power output of the amplifier make it an excellent choice for any audio applications.
