Mono 2.6W Class D Amplifier
General Description
The MAX98300 mono 2.6W Class D amplifier provides Class AB audio performance with Class D efficiency. This device offers five selectable gain settings (0dB, 3dB, 6dB, 9dB, and 12dB) set by a single gain-select input (GAIN).
Active emissions-limiting edge-rate and overshoot con­trol circuitry greatly reduces EMI. A patented filterless spread-spectrum modulation scheme eliminates the need for output filtering found in traditional Class D devices. These features reduce application component count.
The MAX98300 industry-leading 0.78mA at 3.7V (1.1mA at 5V) quiescent current extends battery life in portable applications.
The MAX98300 is available in an 8-pin TDFN-EP (2mm x 2mm x 0.8mm) and a 9-bump (1.2mm x 1.2mm) WLP. Both packages are specified over the extended -40NC to +85NC temperature range.

Mono 2.6W Class D Amplifier
Detailed Description
The MAX98300 features industry-leading quiescent cur­rent, low-power shutdown mode, comprehensive click­and-pop suppression, and excellent RF immunity.
The device offers Class AB audio performance with Class D efficiency in a minimal board-space solution.
The Class D amplifier features spread-spectrum modula­tion, edge-rate, and overshoot control circuitry that offers
MAX98300
significant improvements to switch-mode amplifier radi­ated emissions.
The MAX98300 amplifier features click-and-pop sup­pression that reduces audible transients on startup and shutdown. The amplifier includes thermal overload and short-circuit protection.
Class D Speaker Amplifier
The MAX98300 filterless Class D amplifier offers much higher efficiency than Class AB amplifiers. The high efficiency of a Class D amplifier is due to the switching operation of the output stage transistors. Any power loss associated with the Class D output stage is mostly due to
2
R loss of the MOSFET on-resistance and quiescent
the I current overhead.
Ultra-Low EMI Filterless Output Stage
Maxim’s patented spread-spectrum modulation mode flattens wideband spectral components, while propri­etary techniques ensure that the cycle-to-cycle variation of the switching period does not degrade audio repro­duction or efficiency. The MAX98300’s spread-spectrum modulator randomly varies the switching frequency by Q10kHz around the center frequency (300kHz). Above 10MHz, the wideband spectrum looks like noise for EMI purposes (Figure 1).
Speaker Current Limit
If the output current of the speaker amplifier exceeds the current limit (2A typ), the MAX98300 disables the out­puts for approximately 130Fs. At the end of 130Fs, the outputs are re-enabled. If the fault condition still exists, the MAX98300 continues to disable and re-enable the outputs until the fault condition is removed.
Selectable Gain
The MAX98300 offers five programmable gain selections through a single gain input (GAIN).

Shutdown
The MAX98300 features a low-power shutdown mode, drawing less than 0.1FA of supply current. Drive SHDN low to put the MAX98300 into shutdown.
Click-and-Pop Suppression
The MAX98300 speaker amplifier features Maxim’s com­prehensive click-and-pop suppression. During startup, the click-and-pop suppression circuitry reduces any audible transient sources internal to the device. When entering shutdown, the differential speaker outputs ramp down to PGND quickly and simultaneously.
Applications Information
Filterless Class D Operation
Traditional Class D amplifiers require an output filter. The filter adds cost, size, and decreases efficiency and THD+N performance. The MAX98300’s filterless modula­tion scheme does not require an output filter (Figure 1).
Because the switching frequency of the MAX98300 is well beyond the bandwidth of most speakers, voice coil movement due to the switching frequency is very small. Use a speaker with a series inductance > 10FH. Typical 8I speakers exhibit series inductances in the 20FH to 100FH range.
Component Selection
Speaker Amplifier Power Supply Input (PVDD)
PVDD powers the speaker amplifier. PVDD ranges from 2.6V to 5.5V. Bypass PVDD with a 0.1FF and 10FF capacitor to PGND. Apply additional bulk capacitance at the device if long input traces between PVDD and the power source are used.
Input Filtering
The input-coupling capacitor (C amplifier’s internal input resistance (R pass filter that removes the DC bias from the incoming signal. These capacitors allow the amplifier to bias the signal to an optimum DC level.

tors with adequately low voltage-coefficient for best low­frequency THD performance.
Layout and Grounding
Proper layout and grounding are essential for optimum performance. Good grounding improves audio perfor­mance and prevents switching noise from coupling into the audio signal.
Use wide, low-resistance output traces. As load imped­ance decreases, the current drawn from the device outputs increase. At higher current, the resistance of the output traces decreases the power delivered to the load. For example, if 2W is delivered from the speaker output to a 4I load through a 100mI trace, 49mW is consumed in the trace. If power is delivered through a 10mI trace, only 5mW is consumed in the trace. Wide output, supply, and ground traces also improve the power dissipation of the device.
The MAX98300 TDFN-EP package features an exposed thermal pad on its underside. This pad lowers the pack­age’s thermal resistance by providing a heat conduction path from the die to the PCB. Connect the exposed ther­mal pad to the ground plane by using a large pad and multiple vias.
