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.
