LM4912 Product details

Description

The LM4912 is an stereo audio power amplifier capable of delivering 40mW per channel of continuous average power into a 16Ω load or 25mW per channel into a 32Ω load at 1% THD form a 3V power supply.

Features

a low-power consumption shutdown mode and a power mute mode that allows for faster turn on time with less than 1mV voltage change at outputs on release. Additionally, the LM4912 features an internal thermal shutdown protection mechanism. The LM4912 is unity gain stable and may be configured with external gain-setting resistors. Key Specifications n PSRR at 217 Hz and 1kHz 65dB (typ) n Output Power at 1kHz with VDD = 2.4V, 1% THD+N into a 16Ω load 25mW (typ) n Output Power at 1kHz with VDD = 3V,.
