Drives 4

Ω and 8Ω Loads

delivering 11W per channel of continuous average

•

Internal Gain Resistors (AV = 34 dB)

output power to a 4

Ω load, or 7W per channel into 8Ω

•

Minimum External Component Requirement

using a single 24V supply at 10% THD+N.

•

Single Supply Operation

The LM4752 is specifically designed for single supply
