LM4820IBP-6-LM4820M-6-LM4820MX-6
Fixed Gain 1 Watt Audio Power Amplifier
LM4820-6
Fixed Gain1 Watt Audio Power Amplifier
General Description

The LM4820-6isan audio power amplifier primarily de-
signedfor demanding applicationsin mobile phones and
other portable communication device applications.Itis ca-
pableof delivering1 wattof continuous average powertoan BTL load with less than1% distortion (THD+N)at 6dBof
BTL gain froma 5VDC power supply.
Boomer audio power amplifiers were designed specificallyto
provide high quality output power witha minimal amountof
external components. The LM4820-6 doesnot require input
and gain resistors, output coupling capacitorsor bootstrap
capacitors, and thereforeis ideally suitedfor mobile phone
and other low voltage applications where minimal parts
count and low power consumptionisa primary requirement.
The LM4820-6 featuresa low-power consumption shutdown
mode, whichis achievedby driving the shutdownpin with
logic low. Additionally, the LM4820-6 featuresan internal
thermal shutdown protection mechanism.
The LM4820-6 contains advanced pop& click circuitry which
eliminates noises which would otherwise occur during
turn-on and turn-off transitions.
Key Specifications
Improved PSRRat 217Hz 62dB Power Outputat 5.0V& 1% THD 1.0W(typ.) Power Outputat 3.3V& 1% THD 400mW(typ.) Shutdown Current 0.1µA(typ.)
Features
Fixed 6dB BTL voltage gain Availablein space-saving packages micro SMD, MSOP
and SOIC Ultra low current shutdown mode Can drive capacitive loadsupto 500pF Improved pop& click circuitry eliminates noises during
turn-on and turn-off transitions 2.0- 5.5V operation No output coupling capacitors, snubber networksor
bootstrap capacitors required External gain configuration still possible
Applications
Mobile Phones PDAs Portable electronic devices
