MAX98300
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 con-
trol 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.

MAX98300
Mono 2.6W Class D Amplifier
Detailed Description
The MAX98300 features industry-leading quiescent cur-
rent, low-power shutdown mode, comprehensive click-
and-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 modula-
tion, edge-rate, and overshoot control circuitry that offers
significant improvements to switch-mode amplifier radi-
ated emissions.
The MAX98300 amplifier features click-and-pop sup-
pression 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
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 electromag-
netic-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.
Maxim’s patented spread-spectrum modulation mode
flattens wideband spectral components, while propri-
etary techniques ensure that the cycle-to-cycle variation
of the switching period does not degrade audio repro-
duction 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 out-
puts 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).

Mono 2.6W Class D Amplifier
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 com-
prehensive 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 modula-
tion 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 (CIN), in conjunction with the
amplifier’s internal input resistance (RIN), forms a high-
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.
Assuming zero source impedance with a gain setting of
AV = 6dB, 9dB, or 12dB, CIN is:
IN 3dB

C [ F]
f−

with a gain setting of AV = 3dB, CIN is:

5.7
C [ F]
f−

with a gain setting of AV = 0dB, CIN is:
IN 3dB
4
C [ F]
f−
= µ
where f-3dB is the -3dB corner frequency. Use capaci-
tors with adequately low voltage-coefficient for best low-
frequency THD performance.
Layout and Grounding
Proper layout and grounding are essential for optimum
performance. Good grounding improves audio perfor-
mance and prevents switching noise from coupling into
the audio signal.
Use wide, low-resistance output traces. As load imped-
ance 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 pack-
age’s thermal resistance by providing a heat conduction
path from the die to the PCB. Connect the exposed ther-
mal pad to the ground plane by using a large pad and
multiple vias.
