Mono 2W Class D Amplifier
MAX9830
General Description
Features
The MAX9830 mono 2W Class D amplifier provides
Class AB audio performance with Class D efficiency.
o Industry-Leading Quiescent Current: 1.6mA at 5V,
1.2mA at 3.6V
Active emissions limiting edge rate and overshoot con-
trol circuitry greatly reduces EMI. A filterless spread-
spectrum modulation scheme eliminates the need for
output filtering found in traditional Class D devices.
These features reduce application component count.
o Spread Spectrum and Active Emissions Limiting
o Passes EMI Limit Unfiltered with Up to 24in
(61cm) of Speaker Cable
o Click-and-Pop Suppression
The MAX9830’s industry-leading 1.6mA at 5V, 1.2mA at
3.6V, quiescent current extends battery life in portable
applications.
o Thermal and Overcurrent Protection
o Low 0.5µA Current Shutdown Mode
The MAX9830 is available in an 8-pin TDFN (2mm x
2mm x 0.8mm) and is specified over the extended
-40°C to +85°C temperature range.

The MAX9830 offers Class AB audio performance with
Class D efficiency in a minimal board-space solution.
The Class D amplifier features spread-spectrum modu-
lation combined with edge rate and overshoot control
circuitry that offers significant improvements to switch-
mode amplifier radiated emissions.

(600kHz). Above 10MHz, the wideband spectrum looks
like noise for EMI purposes (Figure 1).
Class D Speaker Amplifier
The MAX9830 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.
Speaker Current Limit
If the output current of the speaker amplifier exceeds
the current limit (1.8A typ), the MAX9830 disables the
outputs for approximately 400µs. At the end of 400µs,
the outputs are re-enabled. If the fault condition still
exists, the MAX9830 continues to disable and re-enable
the outputs until the fault condition is removed.
Ultra-Low EMI Filterless Output Stage
Traditional Class D amplifiers require the use of exter-
nal LC filters, or shielding, to meet EN55022B electro-
magnetic-interference (EMI) regulation standards.
Maxim’s active emissions limiting edge-rate control cir-
cuitry and spread-spectrum modulation reduces EMI
emissions, while maintaining up to 85% efficiency.
Shutdown
The MAX9830 features a low-power shutdown mode,
drawing 0.5µA of supply current. Drive SHDN low to put
the MAX9830 into shutdown.
Click-and-Pop Suppression
The MAX9830 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.
Maxim’s spread-spectrum modulation mode flattens
wideband spectral components, while proprietary tech-
niques ensure that the cycle-to-cycle variation of the
switching period does not degrade audio reproduction
or efficiency. The MAX9830’s spread-spectrum
modulator randomly varies the switching
frequency by 10kHz around the center frequency

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 MAX9830’s filterless modula-
tion scheme does not require an output filter.
the amplifier’s internal input resistance (R ), forms a
IN
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. Select 0.47µF
capacitors for optimum click-and-pop performance and
17Hz f

Because the switching frequency of the MAX9830 is
well beyond the bandwidth of most speakers, voice coil
movement at the switching frequency is very small. Use
a speaker with a series inductance > 10µH. Typical 8Ω
speakers exhibit series inductances in the 20µH to
100µH range.

Component Selection
Optional Ferrite Bead Filter
Use capacitors with adequately low voltage-coefficient
for best low-frequency THD performance.
Although not normally needed, in applications where
speaker leads exceed 24in at V
= 3V, use a filter
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.
PVDD
constructed from an inexpensive ferrite bead and a
small-value capacitor to ground (Figure 2) to provide
additional EMI suppression. Use a ferrite bead with low
DC resistance, high frequency (≥ 1MHz) impedance of
100Ω to 600Ω, and rated for at least 1A. The capacitor
value varies based on the ferrite bead chosen and the
actual speaker lead length. Select the capacitor value
based on EMI performance.
Use wide, low-resistance output traces. As load imped-
ance decreases, the current drawn from the device out-
puts 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 4Ω load through a 100mΩ trace, 49mW is con-
sumed in the trace. If power is delivered through a
10mΩ trace, only 5mW is consumed in the trace. Wide
output, supply and ground traces also improve the
power dissipation of the device.
Speaker Amplifier Power Supply Input (PVDD)
PVDD powers the speaker amplifier. PVDD ranges from
2.6V to 5.5V. Bypass PVDD with a 0.1µF capacitor to
PGND. Apply additional bulk capacitance at the device
if long input traces between PVDD and the power
source are used. Ensure a rate of voltage rise at PVDD
is limited to 1V/µs.
The MAX9830 is inherently designed for excellent RF
immunity. For best performance, add ground fills
around all signal traces on top and bottom PCB planes.
The MAX9830 TDFN package features an exposed
thermal pad on its underside. This pad lowers the pack-
age’s thermal resistance by providing a heat conduc-
tion path from the die to the PCB. Connect the exposed
thermal pad to the ground plane by using a large pad
and multiple vias.
