Product details

Description

The LM49100 is a fully integrated audio subsystem capable of delivering 1.275W of continuous average power into a mono 8Ω bridged-tied load (BTL) with 1% THD+N and with a 5V power supply.

Features

a 32-step digital volume control and ten distinct output modes. The mixer, volume control, and device mode select are controlled through an I2C compatible interface. Thermal overload protection prevent the device from being damaged during fault conditions. Superior click and pop suppression eliminates audible transients on power-up/down and during shutdown. Key Specifications.
Power Output at VDD = 5V: Speaker: RL = 8Ω, THD+N ≤ 1% Headphone (VDDHP = 2.8V): RL = 32Ω, THD+N ≤ 1%.
