When using an external amplifier with the ML22Q53X series, can I select a class AB amplifier or a class D amplifier?
When using an external amplifier, select a class AB amplifier. Moreover, LOUT (line amplifier output dedicated terminal) and SPP (line amplifier output settable terminal) are carried in ML22Q53X series. We recommend using LOUT and SPP.
Are fuse reducers required for downsizing ampere ratings of Class L fuses?
No, fuse reducers are not required or available. The bolt hole patterns of Class L fuses are designed to allow you use smaller ampere ratings.
丽正国际中压的MOSFET产品可以做CLASS D功放用吗？
可以的。功放选用MOSFET的时候考虑的因素主要是功率，电压，Rdson，还有开关频率等，这些因素会影响到THD，丽正国际的MOSFET产品可以满足D类功放的设计，但是需要根据产品设计的功放功率来选择一定的MOSFET，还有参数的选型，还有谐波失真的要求，最后再来选型MOSFET，当然MOSFET的选择后再需要设计其它元件一起配合，比如低通滤波器的LC选型等。

In the A/D converter of the ML62Q1000 series, it is said that it is possible to select whether or not to discharge the sample hold capacitance with the SAINIT bit. What is the standard for using with or without discharge?
With no discharge, the charging and discharging of the sample hold capacitor inside the A/D converter is minimized, and the voltage fluctuation of the terminal becomes small, which is effective for A/D conversion of only one channel. With discharge, the phenomenon that the result of the previous A/D conversion affects the next channel is eliminated, and the degree of influence becomes the same each time, so it is effective when performing A/D conversion for two or more channels. However, even with the above settings, there is a concern that the A/D conversion results may be shifted due to fluctuations in the terminal voltage. In this case, it is necessary to take countermeasures such as extending the A/D sample hold time or reducing the frequency of A/D conversion.

What is a offset of the rcoa_adjustOscillation function argument described in the ML62Q1000 Series RC Oscillation Correction Sample Software AP Note?
The offset is a value for adjusting the value writing to the low-speed RC oscillation frequency adjustment register. Normally, please use the fixed value 0 as with the sample software.
For BD37513~515FS,BD37522~524FS,BD37531~534FS,BD37541~BD37543FS, Can the characteristics of the low and high frequency side be symmetrical like BD37034FV?
This is not possible because the circuit is different..
For BD37033FV-M,BD37034FV-M,BD37524FS,BD37534FV,BD37543FS, What is the level meter function?
The Level Meter is a circuit that outputs a DC voltage proportional to the magnitude of the signal and holds the peak level of the detected signal. Since the held peak level can be reset by resetting the Level Meter, the transition of the peak level can be monitored by periodically performing a reset. The reset interval should be at least one cycle of the frequency to be monitored.
What should I do to perform accurate A/D conversion of high frequency signals?
Take an appropriate measure, for example, reduce the input resistance of the A/D conversion pin, input through an amplifier, etc. Related Products: ML610(Q)40x, ML610(Q)42x, ML610(Q)47x, ML610(Q)48x, ML610Q10x, ML610Q11x, ML610Q17x, ML610Q30x, ML610Q35x, ML610Q36x, ML610Q38x, ML610Q41x, ML610Q43x, ML610Q46x, ML620Q13x, ML620Q15x, ML620Q416/ML620Q418, ML620Q503H/ML620Q504H/ML620Q506H, ML62Q12xx, ML62Q13xx, ML62Q14xx, ML62Q15xx/ML62Q18xx, ML62Q16xx, ML62Q17xx
What is the definition of frame frequency of the LCD driver?

Is an antenna included?
In each evaluation kit, an antenna is included for reference. However, the antenna for 800 to 900 MHz is included in any evaluation kit in terms of size, and using it with another frequency band (400 MHz), antenna gain will be worse.

Is it possible to use direct conversion (zero IF)?
Setting is possible. However, the sensitivity is affected because the leakage of local frequency components to the ANT always appears as Co-Channel interference. For this reason, its use is not recommended. Related Products: ML7345/ML7345D, ML7404, ML7414
For Analog Audio Processors, For a product that operates with One or Two Positive Power Supplies, is accurate capacitance value required for the Coupling Capacitor of unused input signal terminals?
Accurate capacitance value is not required, but since the HPF is formed by the Coupling Capacitor and the internal input Resistor, the noise frequency bandwidth that can be filtered varies depending on the capacitance value to be connected.
In the FSK mode, when continuously transmitting the modulated wave using RF_TEST_MODE, the center frequency shifts by about 3 KHz.
As described in the data sheet, when using RF_TEST_MODE in FSK mode, the modulator reads unnecessary data before the generation of the expected test data just after TX_ON is started up. Therefore, the center frequency changes. To use RF_TEST_MODE correctly, check again through the following procedure. 1. Initialization register setting 2. Execute VCO_CAL 3. TX_ON 4. After starting up TX, MODEM reset * Note: Usually, this event does not occur when transmitting packets containing DIO control. So, it is not required to perform a MODEM reset after TX_ON. This is also an event specific to FSK mode. There is no problem in GFSK mode. Related Products: ML7344/ML7406 family, ML7345 family, ML7404, ML7414
