LM4836

Stereo 2W Audio Power Amplifiers

with DC Volume Control, Bass Boost, and Input Mux

General Description

Key Specifications

The LM4836 is a monolithic integrated circuit that provides

DC volume control, and stereo bridged audio power amplifi-

ers capable of producing 2W into 4Ω (Note 1) with less than

1.0% THD+N, or 2.2W into 3Ω (Note 2) with less than 1.0%

THD+N.

Boomer^®audio integrated circuits were designed specifically

to provide high quality audio while requiring a minimum

amount of external components. The LM4836 incorporates a

DC volume control, stereo bridged audio power amplifiers,

selectable gain or bass boost, and an input mux making it

n P_Oat 1% THD+N

into 3Ω (LM4836MTE)

into 4Ω (LM4836MTE)

into 8Ω (LM4836)

2.2W(typ)

2.0W(typ)

1.1W(typ)

1.0%(typ)

n Single-ended mode - THD+N

at 85mW into 32Ω

n Shutdown current

0.2µA(typ)

optimally suited for multimedia monitors, portable radios, Features

desktop, and portable computer applications.

n PC98 and PC99 Compliant

n DC Volume Control Interface

n Input mux

The LM4836 features an externally controlled, low-power

consumption shutdown mode, and both a power amplifier

and headphone mute for maximum system flexibility and

performance.

Note 1: When properly mounted to the circuit board, the LM4836MTE will

deliver 2W into 4Ω. The LM4836MT will deliver 1.1W into 8Ω. See the Appli-

cation Information section for LM4836MTE usage information.

n System Beep Detect

n Stereo switchable bridged/single-ended power amplifiers

n Selectable internal/external gain and bass boost

configurable

n “Click and pop” suppression circuitry

n Thermal shutdown protection circuitry

Note 2: An LM4836MTE which has been properly mounted to the circuit

board and forced-air cooled will deliver 2.2W into 3Ω.

Applications

n Portable and Desktop Computers

n Multimedia Monitors

n Portable Radios, PDAs, and Portable TVs
