LY8210  
2.5 W/CH Stereo Class D Audio power Amplifier (WCSP/ TSSOP)  
Rev. 1.7  
FEATURES  
GENERAL DESCRIPTION  
„ 2.5 W/CH Into 4Ω from 5V power supply at  
THD = 10% (Typ.).  
„ 2.5V~5.5V Power supply.  
„ Low shutdown Current.  
„ Low Quiescent Current.  
The LY8210 is a high efficiency, 2.5 W stereo class  
D audio power amplifier. It is a low noise, filterless  
PWM architecture eliminates the output filter,  
reducing external component count, system cost,  
and simplify design.  
„ Minimum external components.  
„ No output filter required for inductive loads.  
„ Output Pin Short-Circuit Protection (Short to  
Output Pin, Short to GND, Short to VCC)  
„ Low noise during turn-on and turn-off transitions.  
„ Lead free and green package available.  
(RoHS Compliant)  
„ Wafer Chip Scale (WCSP) and TSSOP 20 pin  
packaging available.  
The LY8210 is designed to meet of Multimedia  
application includes mobile phones and other  
portable electronic devices. The LY8210 is a single  
5V supply, it is capable of driving 4Ω speaker load at  
a continuous average output of 2.5 W/CH with 10%  
THD+N.  
In cellular handsets, the earpiece, speaker phone,  
and melody ringer can each be driven by the  
LY8210. Output pin short circuit ( short to output pin,  
short to ground and short to VDD ) protection  
prevent the device from damage during fault  
conditions.

APPLICATION INFORMATION  
Fully Differential Amplifier  
The LY8210 is a fully differential amplifier with differential inputs and outputs. The fully differential amplifier  
consists of a differential amplifier and a common-mode amplifier. The differential amplifier ensures that the  
amplifier outputs a differential voltage on the output that is equal to the differential input times the gain. The  
common-mode feedback ensures that the common-mode voltage at the output is biased around VDD/2  
regardless of the common-mode voltage at the input. The fully differential LY8210 can still be used with a  
single-ended input; however, the LY8210 should be used with differential inputs when in a noisy environment,  
like a wireless handset, to ensure maximum noise rejection.

2.5 W/CH Stereo Class D Audio power Amplifier (WCSP/ TSSOP)  
Rev. 1.7  
Input Resistors (Ri) and Gain  
The LY8210 has two internal amplifier stages. The pre-amplifier gain is externally configurable, while the total  
gain is internally fixed. The closed-loop gain of the pre-amplifier gain is set by selecting the Rf to Ri while the  
total gain is fixed at 2x. So the input resistors (Ri) set the gain of the amplifier according to the equation.  
Pre-Amplifier Gain = Rf / Ri  
Total Gain = (Rf / Ri ) x 2  
AVD = 20 x log [2 x (Rf /Ri )]  
The resistor matching is very important in the amplifiers. Balance of the output on the reference voltage  
depends on matched ratio of the resistors. CMRR, PSRR, and cancellation of the second harmonic distortion  
if resistor mismatch occurs. Therefore, it is recommended to use 1% tolerance resistors or better to keep the  
performance optimized. Matching is more important than overall tolerance.  
Resistor arrays with 1% matching can be used with a tolerance greater than 1%.Place the input resistors very  
close to the LY8210 to limit noise injection on the high-impedance nodes. For optimal performance the gain  
should be set to 2 V/V or lower. Lower gain allows the LY8210 to operate at its best,

Input Capacitors (Ci)  
The LY8210 using fully differential source, So the input coupling capacitors are required. The input capacitors  
and input resistors form a high-pass filter with the corner frequency(fc), determined in the equation.  
fc = 1 / ( 2πRi Ci )  
The value of the input capacitor is important to consider as it directly affects the bass (low frequency)  
performance of the circuit. Speakers in wireless phones cannot usually respond well to low frequencies, so  
the corner frequency can be set to block low frequencies in this application. Equation is reconfigured to solve  
for the input coupling capacitance.  
Ci = 1 / ( 2πRi fc )  
If the corner frequency is within the audio band, the capacitors should have a tolerance of ±10% or better,  
because any mismatch in capacitance causes an impedance mismatch at the corner frequency and below.

Decoupling Capacitor (CS)  
The LY8210 is a high-performance class-D audio amplifier that requires adequate power supply decoupling to  
ensure the efficiency is high and total harmonic distortion (THD) is low. For higher frequency transients,  
spikes, or digital hash on the line, a good low equivalent-series-resistance (ESR) ceramic capacitor, typically  
1.0uF, placed as close as possible to the device VDD lead works best. Placing this decoupling capacitor close  
to the LY8210 is very important for the efficiency of the class-D amplifier, because any resistance or  
inductance in the trace between the device and the capacitor can cause a loss in efficiency. For filtering  
lower-frequency noise signals, a 10.0uF or greater capacitor placed near the audio power amplifier would also  
help, but it is not required in most applications because of the high PSRR of this device.  
PCB Layout  
All the external components must place very close to the LY8210. The input resistors need to be very close to  
the LY8210 input pins so noise does not couple on the high impedance nodes between the input resistors and  
the input amplifier of the LY8210. Then place the decoupling capacitor Cs, close to the LY8210 is important  
for the efficiency of the class-D amplifier. Any resistance or inductance in the trace between the device and  
the capacitor can cause a loss in efficiency.  
Making the high current traces going to VDD, GND, VO+ and VO- pins of the LY8210 should be as wide as  
possible to minimize trace resistance. If these traces are too thin, the LY8210's performance and output  
power will decrease. The input traces do not need to be wide, but do need to run side-by-side to enable  
common-mode noise cancellation.
