LME49830
Mono High Fidelity 200 Volt MOSFET Power Amplifier Input
Stage with Mute
General Description
The LME49830 is a high fidelity audio power amplifier input
stage designed for demanding consumer and pro-audio ap-
plications. Amplifier output power may be scaled by changing
the supply voltage and number of output devices. The
LME49830 is capable of driving an output stage in excess of
300 W single-ended into an 8
load in the presence of 10%
high line headroom and 20% supply regulation.
The LME49830 includes internal thermal shut down circuitry
that activates when the LME49830 die temperature exceeds
150°C. The LME49830 has a mute function that mutes the
input drive signal and forces the amplifier output to a quies-
cent state.
The LME49830 has high drive current, 56mA typical, and high
output voltage swing for maximum flexibility in output stage
choice. With a bias voltage range up to 16V the LME49830
can be used to drive MOSFET output stages using a wide
selection of MOSFETs.
The LME49830 has a wide operating supply range of ±20V
to ±100V, which allows lower cost, unregulated power sup-
plies to be used.
