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 4x. So the input resistors (Ri) set the gain of the amplifier according to the equation. Pre-Amplifier Gain = Rf / Ri Output=SE Mode: Total Gain = (Rf / Ri ) x 4 AVD = 20 x log [4 x (Rf /Ri )] For example Table 1. Typical Total Gain and AVD Values (SE Mode) Rf (KΩ) 50 100 150 200 250 300 Ri (KΩ) 50 50 50 50 50 50 Total Gain 4 8 12 24 20 24 AVD (db) 12.04 18.06 21.58 24.08 26.02 27.6 Output=BTL Mode: Total Gain = (Rf / Ri ) x 8 AVD = 20 x log [8 x (Rf /Ri )] For example Table 2.

Ri is 50 kand the specification calls for a flat bass response down to 30 Hz. Ci = 1 / ( 2πRi fc) Ci = 1 / ( 2π x 50KΩ x 30Hz)=0.106uF，One would likely choose a value of 0.1uF as this value is commonly used. Note that it is important to Ci must be 10 times smaller than the bypass capacitor to reduce clicking and popping noise from power on/off and entering and leaving shutdown. After sizing Ci for a given cutoff frequency, size the bypass capacitor to 10 times that of the input capacitor. Ci ≦ Cbypass Bypass Capacitor (Cbypass) The Bypass Capacitor (C3 ) is the most critical capacitor and serves important functions. During start-up or recovery from shutdown mode, Cbypass determines the rate at which the amplifier starts up. The Cbypass will to reduce noise caused by the power supply coupling into the output drive signal. This noise is from the internal analog reference to the amplifier, which appears as degraded the PSRR and THD+N values. The bypass capacitor (C3 ) with values of 1.0μF to 10.0μF is recommended for the best THD and noise performance. Therefore, increasing the bypass capacitor reduces clicking and popping noise from power on/off and entering and leaving shutdown. To have minimal pop, Cbypass should be 10 times larger than Ci. Cbypass ≧ Ci Power Supply Decoupling Capacitor (CS) The LY8361 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 0.1uF~1.0uF, placed as close as possible to the device PVCC lead works best. Placing this decoupling capacitor close to the LY8361 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 1000uF or greater capacitor placed near the audio power amplifier would also help, so 2000uF or larger capacitor should be placed on each PVCC terminal. Single-Ended Output Capacitor, (CO) In single-ended (SE) applications, the dc blocking capacitor forms a high-pass filter with the speaker impedance. The frequency response rolls off with decreasing frequency at a rate of 20 dB/decade. The cutoff frequency is determined by fc = 1 / (2πRLCo) Speaker Load (Ω) 4 6 8 Table 3.

There are several possible configurations, depending on the speaker impedance and whether the output configuration is single-ended (SE) or bridge-tied load (BTL). Table 4 lists the recommended values for the filter components. It is important to use a high-quality capacitor in this application. Table 4. Recommended Filter Output Components Reference Values Output Type Speaker Load (Ω) Filter Inductor (uH) Filter Capacitor (uF) Bridge Tied Load (BTL) 8 22 0.68 8 33 0.47 Single Ended (SE) 4 22 0.68 BST Capacitors The half H-bridge output stages use only NMOS transistors. Therefore, they require bootstrap capacitors for the high side of each output to turn on correctly. A 1.0 ceramic capacitor, rated for at least 25V up, must be connected from each output to its corresponding bootstrap input. Specifically, all 1.0 capacitor must be connected from OUT to BST pin. The bootstrap capacitors connected between the BST pins and their corresponding outputs function as a floating power supply for the high-side N-channel power MOSFET gate-drive circuitry. During each high-side switching cycle, the bootstrap capacitors hold the gate-to-source voltage high enough to keep the high-side MOSFETs turned on. VCLAMP Capacitor To ensure that the maximum gate-to-source voltage for the NMOS output transistors is not exceeded, one internal regulator clamps the gate voltage. A 1.0uF capacitor must be connected from VCLAMP pin to ground and must be rated for 25V up. The voltages at the VCLAMP terminal may vary with PVCC and may not be used for powering any other circuitry. Shutdown Function When the LY8361 not in use. The device will be to turn off the amplifier to reduce power consumption. When logic low is applied to the shutdown pin, this shutdown feature will turns the amplifier off. By switching the shutdown pin connected to GND, the device supply current draw will be minimized in idle mode. The pin cannot be left floating due to the internal did not pull-up. Mute Function The Mute pin is an input pin to control the LY8361 output state. A logic high is disable the LY8361 outputs. A logic low on this pin enables the outputs. This terminal may be used as a quick disable/enable of outputs when changing channels on a TV or transitioning between different audio sources. The Mute pin should never be left floating. For power conservation, the SD pin should be used to reduce the quiescent current to the absolute minimum level. Over-Heat Protection and Automatic Recovery The LY8361 has a built-in over-heat protection circuit, it will turn off all power output when the chip temperature over 180℃, the chip will return to normal operation automatically after the temperature cool down to 160℃. Short Circuit Protection and Automatic Recovery The LY8361 has short-circuit protection circuitry on the outputs that prevents damage to the device during Output pin-to-output pin shorts, output-to-GND shorts, and output-to-PVCC shorts.

If the short was not removed, the protection circuitry again activates until the short is removed. DC Volume Control The DCV pin controls the all mode (SE/BTL/2.1CH/PBTL) volume when driving speakers. This pin is controlled with a dc voltage, which should not exceed AVDD voltage. The output volume increases in discrete steps as the dc voltage increases and decreases in discrete steps as the dc voltage decreases. There are a total of 32 discrete gain steps of the amplifier and range from -56 dB to 32 dB for all mode operation. PBTL (Mono) Configuration The LY8231 features a mono mode that allows the right and left channels to operate in parallel, achieving up to 60W of output power with external heat sink. Connect OUT_A to OUT_B and OUT_C to OUT_D using heavy PCB traces as close as possible to the device. Also in PBTL(mono) and 2.1CH mode, the IN1、O1、IN2、O2 pin can becomes a Hi/Lo pass filter operational amplifier, allowing for flexibility in system design and reducing external component count. PCB Layout Because the LY8361 is a class-D amplifier that switches at a high frequency, the layout of the PCB should be optimized according to the following guidelines for the best possible performance. 1. Thermal pad—The thermal pad must be soldered to the PCB for proper thermal performance and optimal reliability. Then the LY8361 must be mounted to the PCB board and increase a large area of copper or recommended to use external heat sink. But when total output power ≧40W, the device must be use external heat sink. 2. Decoupling capacitors—The high-frequency 0.1uF decoupling capacitors should be placed as close to the PVCC pins and AVCC pin terminals as possible. And the Bypass pin capacitor and VCLAMP pin capacitor should also be placed as close to the device as possible. Large (2000uF or greater) bulk power-supply decoupling capacitors should be placed near the device on the PVCC terminals. 3. Grounding—The AVCC pin decoupling capacitor and Bypass pin capacitor should each be grounded to analog ground (AGND). The PVCC decoupling capacitors and VCLAMP capacitors should each be grounded to power ground (PGND). Analog ground and power ground should be connected at the thermal pad, which should be used as a central ground connection or star ground for the LY8361. 4. Output filter—The reconstruction filter should be placed as close to the output terminals as possible for the best EMI performance. The capacitors should be grounded to power ground. 5. The input resistors need to be very close to the device input pins so noise does not couple on the high impedance nodes between the input resistors and the input amplifier of the device. 6. Making the high current traces going to PVCC, GND, VO+ and VO- pins of the device should be as wide as possible to minimize trace resistance. If these traces are too thin, the device’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.
