Fekete szín - AD8421 erősítő modul műszer erősítő millivoltos mikrovoltos kis jel árnyékoló dobozzal
2 210 Ft 3 745 FtAD8421 Amplifier Module Instrumentation Amplifier Millivolt Microvolt Small Signal With Shielding Box
1. The AD8421 is a low cost, low power, extremely low noise, ultralow bias current, high speed instrumentation amplifier that is perfect suited for a broad spectrum of signal conditioning and data acquisition applications. This product features extremely high CMRR, allowing it to extract low level signals in the presence of high frequency common-mode noise over a wide temperature range.
2. The 10 MHz bandwidth, 35 V/μs slew rate, and 0.6 μs settling time to 0.001% (G = 10) allow the AD8421 to amplify high speed signals and excel in applications that require high channel count, multiplexed systems. Even at higher gains, the current feedback architecture maintains high performance; The AD8421 has excellent distortion performance, making it suitable for use in demanding applications such as vibration analysis.
3. The AD8421 delivers 3 nV/√Hz input voltage noise and 200 fA/√Hz current noise with only 2 mA quiescent current, making it a perfect choice for measuring low level signals. For applications with high source impedance, the AD8421 employs innovative process technology and design techniques to provide noise performance that is limited only by the sensor.
4. The AD8421 uses unique protection methods to ensure robust inputs while still maintaining very low noise. This protection allows input voltages up to 40 V from the opposite supply rail without damage to the part. A single resistor sets the gain from 1 to 10,000. The reference pin can be used to apply a precise offset to the output voltage.
5. The AD8421 is specified from −40Celsius to 85Celsius and has typical performance curves to 125Celsius. It is available in 8-lead MSOP and SOIC packages.
1. Low power consumption: The maximum power supply current is 2.3 mA.
2. Low noise: The maximum input voltage noise at 1 kHz is 3.2 nV/√Hz; Current noise at 1 kHz: 200 fA/√Hz (at 1 kHz).
3. Excellent communication characteristics: Bandwidth: 10 MHz (G = 1); Bandwidth: 2 MHz (G = 100); 0.001% settling time: 0.6 µs (G = 10)br />3. Excellent communication characteristics: Bandwidth: 10 MHz (G = 1); Bandwidth: 2 MHz (G = 100); 0.001% settling time: 0.6 µs (G = 10); Common mode rejection ratio (CMRR): 80 dB (20 kHz, G = 1). 35 V/µs slew rate
4. High precision DC performance (AD8421BRZ)
CMRR: 94 dB (minimum value, G = 1)
Input offset voltage drift: 0.2 µV/Celsius (maximum)
Maximum gain drift: 1 ppm/Celsius (G = 1)
Input bias current: 500 pA (maximum)
5. Input overvoltage protection: Input overvoltage protection can exceed 40V of reverse power supply
6. Gain: The gain is set by a single resistor (G = 1 to 10,00); Default: 10 times gain, you can adjust the gain through the potentiometer.
Wide power supply range: Single power supply: 5V to 36 V

1. How to choose a power supply? The power supply with the board is critical. The higher the voltage, the higher the current and the better the output power. If you only have 12V 1A, you can bring a 3-4 inch speaker. If you are 19V 5A or above, there is no problem with 8-10 inches, and the power supply must be highly valued. If the voltage is too low, the sound will be distorted after the sound is amplified.
If the current is too small, the speaker will pull the voltage low, work abnormally or the sound quality will deteriorate. It is recommended to use 18V19V24V power supply with current above 3A. If you only have 9V12V or 1A 2A power supply, it can also be used but the power is small. Please pay attention to the maximum volume when using it, which may affect the sound quality.
2. How to choose a speaker? Commonly used speakers are generally 4 ohms or 8 ohms, can not distinguish between positive and negative, the effect is the same.If your speaker power is small, it may be used between 10W-30W. The power supply voltage is small to prevent the amplifier from burning out after burning. For example, select a power supply below 15V. If you are a 50W-100w speaker, don't worry about the speaker burnout. You can choose 12-24V power supply.
The higher the voltage you choose, the louder the output sound or power.The speaker power is not recommended to exceed 100W, otherwise the sound quality will be affected.
3. Introduction of audio input mode. This audio amplifier module has two audio input modes: one is bluetooth input and the other is AUX input. Bluetooth mode is preferred.Bluetooth can be connected in either mode.As long as the bluetooth connection is successful is bluetooth mode, and bluetooth mode support automatic connection. AUX insertion is AUX mode when bluetooth is connectionless. It is important to make sure that the bluetooth connection of this
How to adjust the bass and high pitch?
The BASS potentiometer in the middle is to control the BASS, the right BASS is enhanced, the left BASS is attenuated.When the potentiometer is in the middle position, the bass is neither enhanced nor attenuated.
The TREBLE potentiometer on the left controls the TREBLE. the right TREBLE enhanced and the left TREBLE attenuated.When the potentiometer is in the middle position, it does not increase or decrease the treble.
Note when adjusting treble and bass: when the treble or bass right rotation is adjusted to the maximum, if the sound is distorted, it means that the treble or bass gain is too large. It is necessary to turn the treble or bass potentiometer to the left to reduce the gain or turn the VOLUME potentiometer to the left to reduce the total volume.
When the sound becomes louder, the phenomenon of turbid sound appears.
The sound is distorted. Please change the adapter power supply with a higher voltage rating.
After the sound becomes louder, the sound is stuck.
The input power is insufficient, and the power supply itself is intermittently powered off. Please replace the power supply with a larger power.
