Detailed Description

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. Non-clipping power limit, which uses 41-step automatic gain control. Thermal foldback, which reduces output power as the chip heats up. External audio feedback pins, which allow for customization of sound by using feedback network design. Alternatively, these pins can be used for Kelvin connection to speaker terminals. GAIN pin to program audio gain at 0.5dB steps such that external resistors are not required to adjust gain, which can result in gain error. Out-of-audio switching for the boost converter, which minimizes audible noise coming from components on the board. Protection 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.
