General Description
The MAX98307/MAX98308 fully differential mono Class
DG multilevel power amplifiers with integrated inverting
charge pumps offer highly efficient, high-power audio
solutions for portable applications.
Class DG multilevel modulation extends the dynamic
range of the output signal by employing a charge-pump-
generated negative rail as needed to extend the supply
range. This scheme results in high efficiency over a wide
output power range.
The ICs combine Maxim’s active emissions limiting edge
rate and overshoot control circuitry with multilevel out-
put modulation to greatly reduce EMI. These features
eliminate the need for output filtering as compared to
traditional Class D devices, reducing component count
and cost.
The MAX98307’s 16-pin TQFN package features an
adjustable gain set by external resistors. The MAX98308’s
space-saving 12-bump WLP package features an inter-
nally fixed gain of 8.5dB, 11.5dB, 14.5dB, 17.5dB, and
20.5dB set by a single gain input. Both devices operate
over the extended -40NC to +85NC temperature range.
