General Description
The MAX98302 stereo 2.4W Class D amplifier provides Class AB audio performance with Class D efficiency. This device offers five selectable gain settings (6dB, 9dB, 12dB, 15dB, and 18dB) set by a single gain-select input (GAIN). Active emissions limiting, edge-rate, and overshoot control circuitry greatly reduces EMI. A filterless spreadspectrum modulation scheme eliminates the need for output filtering found in traditional Class D devices. These features reduce application component count. The MAX98302 industry-leading 1.65mA at 3.7V, 2.25mA at 5V, quiescent current extends battery life in portable applications. The MAX98302 is available in a 14-pin TDFN-EP (3mm x 3mm x 0.75mm) package specified over the extended -40NC to +85NC temperature range.

Stereo 2.4W Class D Amplifier MAX98302
Detailed Description
The MAX98302 features industry-leading quiescent current, low-power shutdown mode, comprehensive clickand-pop suppression, and excellent RF immunity. The MAX98302 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. The MAX98302 amplifier features click-and-pop suppression that reduces audible transients on startup and shutdown. The amplifier includes thermal-overload and short-circuit protection. The MAX98302 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. 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 active emissions limiting edge-rate control circuitry and spreadspectrum modulation reduce EMI emissions, while maintaining up to 83% efficiency. Maxim's 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 MAX98302's spread-spectrum modulator randomly varies the switching frequency by Q7kHz around the center frequency (300kHz). Above 10MHz, the wideband spectrum looks like noise for EMI purposes. Speaker Current Limit If the output current of the speaker amplifier exceeds the current limit (2A typ), the MAX98302 disables the outputs for approximately 100Fs. At the end of 100Fs, the outputs are re-enabled. If the fault condition still exists, the MAX98302 continues to disable and re-enable the outputs until the fault condition is removed. The MAX98302 offers five programmable gains selected using the GAIN input.

Class D Speaker Amplifier
The MAX98302 features a low-power shutdown mode, drawing 0.17FA of supply current. Drive SHDN low to put the MAX98302 into shutdown. The MAX98302 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.

Click-and-Pop Suppression
Applications Information
Traditional Class D amplifiers require an output filter. The filter adds cost and size and decreases THD+N performance. The MAX98302's filterless modulation scheme does not require an output filter. Because the switching frequency of the MAX98302 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.
Filterless Class D Operation
Component Selection
Speaker Amplifier Power-Supply Input (PVDD) PVDD powers the speaker amplifier. PVDD ranges from 2.6V to 5.5V. Bypass PVDD with 0.1FF and 10FF capacitors to PGND. Also, connect at least 10FF of system bulk capacitance to PVDD. Apply additional bulk capacitance at the device if long input traces between PVDD and the power source are used.

Stereo 2.4W Class D Amplifier
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. Assuming zero-source impedance with a gain setting of AV = 12dB, 15dB, or 18dB, CIN is: Proper layout and grounding are essential for optimum performance. Good grounding improves audio performance and prevents switching noise from coupling into the audio signal.
Layout and Grounding
MAX98302
CIN =
8 [F] f -3dB
with a gain setting of AV = 9dB, CIN is:
CIN =
5.7 [F] f -3dB
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 decrease 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 MAX98302 is inherently designed for excellent RF immunity. For best performance, add ground fills around all signal traces on top or bottom PCB planes. The MAX98302 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.
with a gain setting of AV = 6dB, CIN is:
CIN =
4 f -3dB
[F]
where f-3dB is the -3dB corner frequency. Use capacitors with adequately low-voltage coefficients for best low-frequency THD performance.
