MP7720DS-LF-Z概述

    MP7720: 20W Class D Mono Single-Ended Audio Amplifier
    Product Introduction
    The MP7720 is a highly efficient Class D mono audio amplifier manufactured by Monolithic Power Systems (MPS). As part of MPS's second-generation fully integrated audio amplifiers, the MP7720 significantly reduces solution size by integrating essential features such as startup/shutdown pop elimination, short-circuit protection circuits, and mute/standby functionality. The device is designed to deliver exceptional performance in various audio applications.
    The MP7720 features a single-ended output structure capable of delivering up to 20W into a 4Ω load, providing high-fidelity sound comparable to Class A/B amplifiers but with efficiencies exceeding 90%. Utilizing MPS's proprietary variable frequency topology, it ensures excellent power supply rejection ratio (PSRR), fast response times, and stable operation on a single power supply.
    Technical Parameters
    Below are the key technical specifications of the MP7720:
    | Parameter | Value |

    | Supply Voltage | 9.5V to 24V |
    | Idle Current (Typical) | 13mA |
    | Short Circuit Current | 5.0A |
    | Output Power | 20W @ 4Ω |
    | THD+N (Total Harmonic Distortion + Noise) @ 1W, 8Ω | 0.04% |
    | Efficiency | 93% @ 20W |
    | Switching Frequency | Up to 1MHz |
    | Maximum Load Resistance | 4Ω or 8Ω |
    | Sleep Mode Quiescent Current | <5µA |
