LM49100GRX/NOPB

Application field and working principle

The LM49100GRX/NOPB is an audio amplifier designed for wide-range of mobile device applications such as mobile phones, tablets, and portable gaming consoles. This device features a low power amplifier with a frequency range of 45Hz to 45KHz, and a power output of up to 1W. It is also capable of bridged operation for higher current delivery. Moreover, the amplifier also offers 94dB of dynamic range for excellent sound quality.

The amplifier is based on a Gain Monted Processional architecture which helps to reduce noise and distortion, allowing it to produce superior sound quality. In order to achieve optimal audio performance, the LM49100GRX/NOPB can be paired with the an audio power management IC. This helps to reduce power dissipation and improves overall system efficiency. In addition, the amplifier can be adjusted to provide various gain settings to suit the needs of different applications.

The LM49100GRX/NOPB can be used in a variety of audio applications including powering speakers for mobile devices, audio processing for personal computers and other audio equipment, amplifying bass frequencies in headphones, and amplifying audio signals in broadcasting and recording consoles. In addition, the device can also be used to drive actuators in robotics and automation applications.

The LM49100GRX/NOPB is powered by a single 5V supply. It includes two high-bandwidth, low-noise differential inputs with input voltage range of 0 to 3V. Each of the differential input stages has a wide common-mode range that provides flexibility in signal handling and high immunity to system noise. Moreover, the amplifier also includes two integrated switching regulators, which allow the device to be used with low-voltage (1V-3V) power sources.

The amplifier also features short-circuit, temperature, and current protection. It also has an open loop gain of up to 20dB and a signal-to-noise ratio of up to 105dB. Additionally, the device has an output power capability of up to 800mW for a single speaker and up to 1W for bridge mode, which allows it to drive up to two speakers.

The LM49100GRX/NOPB is a highly integrated audio amplifier and offers a highly optimized solution for cost-sensitive audio applications. It also enables smaller and more efficient audio systems due to its low power requirement, which helps to reduce overall system cost. This device is ideal for use in mobile phones, tablets, and portable gaming consoles where space, power, and efficiency are at a premium.
