MAX98307/MAX98308

3.3W Mono Class DG Multilevel Audio Amplifier

General Description

Benefits and Features

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.

S High Efficiency Combined with High Output Power

ꢀClass DG Multilevel Modulation Ensures

Maximum Efficiency Over Wide Output Power

Range

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.

S Improves Battery Life

ꢀLow 1.85mA Quiescent Current

S High Output Power at 1% THD+N

ꢀ1.54W at V

ꢀ2.85W at V

= 3.6V, 8I + 68µH Load

= 5V, 8I + 68µH Load

PVDD

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.

S High Output Power at 10% THD+N

ꢀ1.77W at V = 3.6V, 8I + 68µH Load

PVDD

ꢀ3.3W at V

= 5V, 8I + 68µH Load

PVDD

S 84% Efficiency (V

= 3.6V, at 500mW Output)

S Active Emissions Limiting and Class DG Multilevel

Output Modulation Eliminates EMI Output Filtering

Requirement

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.

S Integrated Charge Pump and High Efficiency

Results in Small Solution Size

S Excellent RF Immunity

S Click-and-Pop Suppression

S Thermal and Overcurrent Protection

S Low-Current Shutdown Mode
