产品概述

The MAX98309/MAX98310 mono 1.4W Class AB audio amplifiers offer low quiescent current while maintaining excellent SNR and low 0.008% THD+N. These ICs feature excellent 90dB PSRR and state of the art click-and-pop suppression.

The ICs are offered with an internally fixed 0dB, 3dB, 6dB, and 9dB gain (MAX98310) or an externally set gain (MAX98309) through external resistors.

The MAX98309 feature a 10ms or 100ms pin-selectable turn-on time, while the MAX98310 has a preset 5ms turn-on time.

The MAX98309/MAX98310 are available in a (1.0mm x 1.0mm) 9-bump, 0.3mm pitch WLP, and are specified over the extended -40°C to +85°C temperature range.
