PAM8965 Datasheet PDF (12W STEREO CLASS-D AUDIO AMPLIFIER)

PAM8965 - 12W STEREO CLASS-D AUDIO AMPLIFIER

Description

The PAM8965 is an extremely high-efficiency Class-D stereo audio power amplifier with an integrated synchronous boost converter.

The PAM8965 can drive two channels with 12W each into 4Ω speakers.

The integrated amplifier can achieve system efficiency of 92% (at VBAT = 7.4V).

Features

include under-voltage and over-voltage protection on VBAT, over-voltage protection on PVDD, short circuit protection on all audio outputs, cycle-by-cycle current limit on boost converter, thermal shutdown of the entire system, DC protection for speakers, and an FLT pin that provides a fault flag. Features.
Operates from 2.8V to 8.5V Supply.
2  12W (10% THD+N) into 4Ω Load with VBAT = 7.4V (2SxP).
2  8W (10% THD+N) into 6Ω Load with VBAT = 3.7V (1SxP).
Auto Gain Control Resp.

PAM8965 12W STEREO CLASS-D AUDIO AMPLIFIER WITH SYNCHRONOUS BOOST, SSM AND EXTERNAL AUDIO FEEDBACK Description The PAM8965 is an extremely high-efficiency Class-D stereo audio power amplifier with an integrated synchronous boost converter. The PAM8965 can drive two channels with 12W each into 4Ω speakers. The integrated amplifier can achieve system efficiency of 92% (at VBAT = 7.4V). The device consumes exceptionally low quiescent current (10mA at VBAT = 7.4V) and very low shutdown current (0.7μA). The integrated current-mode boost converter provides regulated power to a feature-laden Class-D stereo amplifier. These include: Spread spectrum modulation (SSM) for EMI suppression (audio and boost), which enables the use of inexpensive ferrite bead filters.
