LM3886 Overture™ Audio Power Amplifier Series

High-Performance 68W A ud i o P ower Amplifier w/Mute

Check for Samples: LM3886

FEATURES

DESCRIPTION

The LM3886 is a high-performance audio power

•

68W Cont. Avg. Output Power into 4Ω at V_CC

±28V

amplifier capable of delivering 68W of continuous

average power to a 4Ω load and 38W into 8Ω with

0.1% THD+N from 20Hz–20kHz.

•

38W Cont. Avg. Output Power into 8Ω at V_CC

±28V

The performance of the LM3886, utilizing its Self

Peak Instantaneous Temperature (°Ke) (SPiKe)

protection circuitry, puts it in a class above discrete

and hybrid amplifiers by providing an inherently,

dynamically protected Safe Operating Area (SOA).

SPiKe protection means that these parts are

completely safeguarded at the output against

overvoltage, undervoltage, overloads, including shorts

to the supplies, thermal runaway, and instantaneous

temperature peaks.

•

50W Cont. Avg. Output Power into 8Ω at V_CC

±35V

135W Instantaneous Peak Output Power

Capability

•

Signal-to-Noise Ratio ≥ 92dB

An Input Mute Function

Output Protection from a Short to Ground or

to the Supplies via Internal Current Limiting

Circuitry

The LM3886 maintains an excellent signal-to-noise

ratio of greater than 92dB with a typical low noise

floor of 2.0µV. It exhibits extremely low THD+N

values of 0.03% at the rated output into the rated

load over the audio spectrum, and provides excellent

linearity with an IMD (SMPTE) typical rating of

0.004%.

•

Output Over-Voltage Protection against

Transients from Inductive Loads

Supply Under-Voltage Protection, not Allowing

Internal Biasing to Occur when |V_EE| + |V_CC| ≤

12V, thus Eliminating Turn-On and Turn-Off

Transients

•

11-Lead TO-220 Package

Wide Supply Range 20V - 94V

APPLICATIONS

•

Component stereo

Compact stereo

Self-powered speakers

Surround-sound amplifiers

High-end stereo TVs
