LN3992 - 1.7W Mono Fully Differential Audio Power Amplifier

General Description

The LN3992 is a 1.7W mono fully-differential amplifier designed to drive a speaker with at least 8Ω impedance while consuming only 20 mm2 total printed-circuit board (PCB) area in most applications.

The device operates from 2.5V to 5.5V, drawing only 4mA of quiescent supply current.

Key Features

  • Designed for Wireless or Cellular Handsets and PDAs.
  • 1.7 W Into 8 Ω From a 5V Supply at THD = 10% (Typ).
  • Low Supply Current: 4 mA (typ )at 5 V.
  • Shutdown Current: 0.01µA ( Typ).
  • Ordering Information.
  • Fast Startup With Minimal Pop.
  • Only Three External Components.
  • Improved PSRR (.
  • 80dB) and Wide Supply Voltage (2.5V to 5.5V) for Direct Battery Operation.
  • Fully Diff.

1.7W Mono Fully Differential Audio Power Amplifier LN3992 ■ General Description The LN3992 is a 1.7W mono fully-differential amplifier designed to drive a speaker with at least 8Ω impedance while consuming only 20 mm2 total printed-circuit board (PCB) area in most applications. The device operates from 2.5V to 5.5V, drawing only 4mA of quiescent supply current. The LN3992 is ideal for PDA/smart phone applications due to features such as −80 dB supply voltage rejection from 2 Hz to 20kHz, improved RF rectification immunity, small PCB area, and a fast startup with minimal pop. ■ Features  Designed for Wireless or Cellular Handsets and PDAs  1.7 W Into 8 Ω From a 5V Supply at THD = 10% (Typ)  Low Supply Current: 4 mA (typ )at 5 V  Shutdown Current: 0.
