LY8006 - 1.4 W Mono Filterless Class D Audio power Amplifier

Datasheet Summary

Description

The LY8006 is a high efficiency, 1.4 W mono class D audio power amplifier.

It is a low noise, filterless PWM architecture eliminates the output filter, reducing external component count, system cost, and simplify design.

The LY8006 is designed to meet of portable electronic devices.

Features

  • 1.4 W Into 8Ω from 5V power supply at THD = 10% (Typ).
  • 2.5V~5.5V power supply.
  • Low shutdown current.
  • Low quiescent current.
  • Minimum external components.
  • No output filter required for inductive loads.
  • Output Pin Short-Circuit Protection (Short to Output Pin, Short to GND, Short to VCC).
  • Low noise during turn-on and turn-off transitions.
  • Easy upgrade Class AB (LY8990/LY8891) to Class D (Pin to Pin Replace).

® Rev. 1.7 1.4 W Mono Filterless Class D Audio power Amplifier (MSOP / DFN) －Compatible with LY8890/8891/8891B Single-Ended Input GENERAL DESCRIPTION The LY8006 is a high efficiency, 1.4 W mono class D audio power amplifier. It is a low noise, filterless PWM architecture eliminates the output filter, reducing external component count, system cost, and simplify design. The LY8006 is designed to meet of portable electronic devices. The LY8006 is a single 5V supply, it is capable of driving 8Ω speaker load at a continuous average output of 1.4 W with 10% THD+N. The LY8006 has high efficiency with speaker loads compared to a typical Class AB amplifier. With a 3.6V supply driving an 8Ω speaker, the LY8006 efficiency for a 400mW power level is 88%.
