LM48520 Product details

Description

The LM48520 integrates a boost converter with a high efficiency Class D stereo audio power amplifier to provide up to 1W/ch continuous power into an 8Ω speaker when operating from 2.7V to 5.0V power supply with boost voltage (PV1) of 5.0V.

Features

a low-power consumption shutdown mode. Shutdown may be enabled by driving the Shutdown pin to a logic low (GND). Also, external leakage is minimized via control of the ground reference via the SWOUT pin . The LM48520 has 4 gain options which are pin selectable via Gain0 and Gain1 pins. Output short circuit prevents the device from damage during fault conditions. Superior click and pop suppression eliminates audible transients during powerup and shutdown. Key Specifications.
Quiescent Power.
