The LM4916MM/NOPB is a stereo mobile phone amplifier from Texas Instruments, specifically designed to improve audio performance in mobile handsets. The LM4916MM/NOPB is a dual audio power amplifier that combines high output power with high efficiency and low power consumption. The device also features gain blocks for stereo input and output stages and a flexible biasing circuit for improved sound quality. The device is fully differential in design and features patented short circuit current limiting circuitry for superior sound quality. The device also provides pop and click suppression for improved handset audio performance.The LM4916MM/NOPB is a power amplifier IC that integrates both a differential input stage and a single ended output stage. The differential input stage is made of integrated operational transconductance amplifier (OTA) transistors connected in differential topology in order to increase signal linearity. This stage is followed by a power output stage made up of two matched power MOSFETs connected in parallel. The power stage provides the maximum possible output power while minimizing losses and minimizing distortion.The LM4916MM/NOPB operates in Class-G mode, meaning it can switch between two voltage rails in order to minimize power consumption. When small or medium signal levels are present at the input, the supply voltage of the device switches to the lower voltage rail. When larger signals are present, the supply voltage switches to the higher voltage rail in order to provide more power. This improves efficiency and reduces power consumption.The LM4916MM/NOPB can be configured to provide either a single-ended output or a differential output. In a single-ended configuration, the differential input stage feeds the power stage, which consists of the two power MOSFETs connected in parallel. This configuration is typically used for peak power outputs greater than 1W. In a differential configuration, the differential input stage feeds the two power MOSFETs connected in bridge configuration. This configuration is typically used for peak power outputs greater than 2W.The LM4916MM/NOPB also offers flexibile Biasing settings, which allows users to tailor the output power and distortion levels according to their specific application requirements. The device also features a slew rate control circuit, which provides faster or slower response times depending on the specific needs of the application. The device also features an active pop and click suppression circuit to minimize turn on/off pops.The LM4916MM/NOPB is well suited to its application field because it offers high performance and high efficiency, combined with low power dissipation. The device is well suited for use in audio amplifiers, mobile handsets and other applications where improved audio performance is desired.
