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 fea-
ture 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 (1.0mm x
1.0mm) 9-bump, 0.3mm pitch WLP. These ICs are speci-
fied over the extended -40NC to +85NC temperature range.
