The LM4925MMX is an audio amplifier that provides an ideal solution for low power, low voltage, and low noise audio applications. It is a one-chip solution for a wide range of audio applications such as cell phones, cameras, and laptops. It is also suitable for use in portable stereo systems, multimedia systems, and music players. This amplifier is designed to optimize low voltage power consumption, improve audio quality, and minimize electromagnetic interference (EMI).

The LM4925MMX features a Thermal Under-Voltage Lockout (TUVLO) circuit, which is a novel current mode active-low voltage protection circuit that prevents overvoltage and/or undervoltage conditions. The TUVLO will shut down the LM4925MMX to prevent system damage and malfunction in the event of an overvoltage or undervoltage condition. This feature makes the LM4925MMX suitable for battery-powered applications such as portable multimedia players, where the battery may be running low.

The LM4925MMX is a fully differential low noise, low voltage audio amplifier. It has a power supply range of 1.62V to 3.6V and a maximum quiescent current of 30mA. It offers a distortion of 0.03% THD+N up to 200mW output at a supply voltage of 2.6V. It achieves a wide dynamic range of 118dB and a robust output power of up to 200mW into a 16Ω load. It is optimized for low noise, low distortion, and low power consumption. It features 100KHz gain-bandwidth and a Stereo Boost of 4dB for improved audio performance and enhanced clarity. The LM4925MMX is designed to eliminate the need for an external bias network, allowing the LM4925MMX to replace other amplifier configurations in many cases.

The LM4925MMX is available in a 24-bump micro SMD package that is ideal for space-constrained applications. It is a fully differential in-amp optimized for both Stereo and mono applications. It supports mono-bridge or mono-difference output configurations. The LM4925MMX also has a unique feature that allows it to be directly connected to a MEMS microphone. This eliminates the need for an external buffer amplifier.

The LM4925MMX is an ideal choice for low voltage, low power, low noise audio applications. It is suitable for a wide range of audio applications including cell phones, cameras, laptops, portable stereo systems, and multimedia systems. The LM4925MMX features low power consumption, robust output power, high dynamic range, and wide gain bandwidth for improved audio performance and clarity.

The LM4925MMX is optimized for both stereo and mono applications and offers a unique feature that eliminates the need for an external bias network.
