Output stages Very high voltage range: - ☑00V Scalable output power Minimum external components External compensation Thermal shutdown of input stage Mute controlĪV receivers Audiophile power amps Pro Audio High voltage industrial applications High output current and voltage for use with MOSFET Wide operating Voltage range Output Voltage Noise (BW = 30kHz) PSRR (DC) Slew Rate THD+N = 1kHz) The LME49830 has a wide operating supply range to ☑00V, which allows lower cost, unregulated power supplies to be used. With a bias voltage range to 16V the LME49830 can be used to drive MOSFET output stages using a wide selection of MOSFETs. The LME49830 has high drive current, 56mA typical, and high output voltage swing for maximum flexibility in output stage choice. The LME49830 has a mute function that mutes the input drive signal and forces the amplifier output to a quiescent state. The LME49830 includes internal thermal shut down circuitry that activates when the LME49830 die temperature exceeds 150☌. The LME49830 is capable of driving an output stage in excess 300 W single-ended into an 8 load in the presence of 10% high line headroom and 20% supply regulation. ![]() Amplifier output power may be scaled by changing the supply voltage and number of output devices. The is a high fidelity audio power amplifier input stage designed for demanding consumer and pro-audio applications. ![]() LME49830 Mono High Fidelity 200 Volt MOSFET Power Amplifier Input Stage with Mute ![]()
