LM4802BLQBD - Audio Power Amplifier

Download the LM4802BLQBD datasheet PDF. This datasheet also covers the LM4802B variant, as both devices belong to the same audio power amplifier family and are provided as variant models within a single manufacturer datasheet.

Description

The LM4802B integrates a Boost Converter with an Audio Power Amplifier to drive Ceramic Speakers in portable applications.

When powered by a 3V supply, it is capable of forcing 12Vp-p across a 2μF + 30Ω bridge-tied-load (BTL) with less than 1% THD+N.

Features

  • 1.
  • 23 Pop & Click Circuitry Eliminates Noise During Turn-On and Turn-Off Transitions.
  • Low, 2μA (Max) Shutdown Current.
  • Low, 12mA (Typ) Quiescent Current.
  • 12Vp-p Mono BTL Output, Load = 2μF + 30Ω, VDD = 3V.
  • Short Circuit Protection.
  • Unity-Gain Stable.
  • External Gain Configuration Capability.
