LM49101 - Mono Class AB Audio Subsystem

Description

The LM49101 is a fully integrated audio subsystem with a mono power amplifier capable of delivering 540mW of continuous average power into an 8Ω BTL speaker load with 1% THD+N using a 3.3V supply.

Features

  • a 32.
  • step digital volume control on the input stage and an 8.
  • step digital volume control on the headphone output stage. The digital volume control and output modes, programmed through a two-wire I2C compatible interface, allows flexibility in routing and mixing audio channels. The LM49101 is designed for cellular phones, PDAs, and other portable handheld.
