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). 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 significant improvements to switch-mode amplifier radiated emissions. 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. 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 Selectable Gain 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 the I2R loss of the MOSFET on-resistance and quiescent current overhead. The MAX98300 offers five programmable gain selections through a single gain input (GAIN). Table 1. Gain Control Configuration GAIN PIN Ultra-Low EMI Filterless Output Stage Traditional Class D amplifiers require the use of external LC filters, or shielding, to meet EN55022B electromagnetic-interference (EMI) regulation standards. Maxim’s patented active emissions-limiting edge-rate control circuitry and spread-spectrum modulation reduces EMI emissions, while maintaining up to 89% efficiency.

EMI with 60cm of Speaker Cable and No Output Filtering 8 _______________________________________________________________________________________ Mono 2.6W Class D Amplifier 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 Assuming zero source impedance with a gain setting of AV = 6dB, 9dB, or 12dB, CIN is: CIN = 8 f −3dB [µF] with a gain setting of AV = 3dB, CIN is: CIN = 5.7 [µF] f −3dB with a gain setting of AV = 0dB, CIN is: CIN = 4 [µF] f −3dB 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). where f-3dB is the -3dB corner frequency. Use capacitors with adequately low voltage-coefficient for best lowfrequency THD performance. 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. Proper layout and grounding are essential for optimum performance. Good grounding improves audio performance and prevents switching noise from coupling into the audio signal. 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 (CIN), in conjunction with the amplifier’s internal input resistance (RIN), forms a highpass filter that removes the DC bias from the incoming signal. These capacitors allow the amplifier to bias the signal to an optimum DC level. Layout and Grounding 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 is inherently designed for excellent RF immunity. For best performance, add ground fills around all signal traces on top or bottom PCB planes. 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. _______________________________________________________________________________________ 9 MAX98300 Shutdown The MAX98300 features a low-power shutdown mode, drawing less than 0.1FA of supply current.
