Welcome to my store! You will find your favorite products. Pass by do not miss.thank you! Product Detail ( ---☆ ayanhu81 shop welcome you to buy it ☆---)Dedicated core instrumentation amplifier, rail-to-rail output, high input impedance, high common mode rejection ratio, low offset and drift, low noise, and high closed-loop gain stability, precision measurement / larger choice.First, the module features:1. The high-end dedicated instrumentation amplifier AD623 core, high accuracy and good linearity.2. single power supply, support 3-5V or 7-30V power supply, easy to use!3. Integrated negative pressure generating module, dual power operation, easy to deal with negative signal / AC signal.4. Power input LC filter, clean and stable to ensure the stability of the signal amplification.5. Built-in negative voltage generator module, only a single supply to dual supply operation, simplify system design.6 . rail-to-rail output, the maximum output swing up to + -VCC, far more than the LM358 / AD620 core products (only to VCC-1.5V).7. 2-1000 times magnification adjustable to adapt to different applications, imports of US bounds potentiometer, the resistance change uniform, steady resistance, the price was up to 10 times more than domestic potentiometer (potentiometer often inferior loose, open, beating, lead to big, sometimes small resistance when open, etc., can not guarantee a stable magnification, it is difficult to ensure accuracy).Second, the model descriptionAD623 module: standard amplifier modules. Enlarge AC / DC signal.Third, the main parameters( ---☆ ayanhu81 shop welcome you to buy it ☆---)Amplifier Type: Special instrumentation amplifier AD623 coreInput range: 0.5VCC (ie voltage S + / S- is less than half the supply voltage.)Output Range: + - VCC (rail to rail)Magnification: 2-1000 times adjustable.Power consumption: 150uA (typical) 650uA (max)Power supply: 3-5V or 7-30VGain Accuracy: 0.35% (G> 2) 0.10% (G = 2)Input offset voltage: 100-200uVInput offset drift: 1uv / ℃Common mode rejection ratio: 90dbGain Bandwidth: 800KHZ.PCB Size: 25 * 30mm.Please refer to the specific parameters of the amplifier AD623 chip information. Fourth, Pin Description:HVCC: high voltage input, this pin when using 7-30V power supply.GND: negative power supply, the amplifier ground.LVCC: power input, whereby the use 3-5V power supply pin.-VCC: Negative voltage output, -5V.AO: amplified output signal5V: 5V output.S-: negative signal input terminalS +: Positive signal input terminal (S + / S- only reference positive and negative impact of the polarity of the output signal is not necessarily greater than S + S-)LV logo: 3V power supply is recommended shorting the negative supply can improve performance (also not connected).A ++ Knob: 2-1000 times magnification adjustment clockwise to increase magnification.REF ++ Knob: Pan voltage regulator, the default is not welding potentiometer (shipping and distribution), then the REF to ground, the output signal is 0V reference. Disconnect shorted pads, welding potentiometer, the output voltage can be adjusted to pan (for example, signal amplification + -100mV 10 times, the default is + -1V output voltage, voltage 0-2V can pan to facilitate the collection).Use the default before shipment adjusted to 10 times magnification, it is recommended to use a smaller magnification (eg 10x) to test the baby, and then transferred to the needs of multiples. A ++ adjustment knob clockwise increases the magnification (up to 1000), when adjusted to the maximum, you can hear the potentiometer minor issue Kaka sound, it means that has been adjusted to the end.Fifth. Notes1. Some people call it the REF pin zero, so there is no problem, but the high precision core AD623, REF directly to ground, the output that is very close to zero, actually no adjustment. It recommended that only need voltage translation time, and then connect this potentiometer.2. We use the imported US bounds potentiometer to adjust the uniformity, stability, high reliability, higher than the domestic price of potentiometer 10 times, non-comparable general domestic potentiometer.3. AD623 offset voltage is 200uv, ie, the maximum error may occur 200uv on the input voltage, if the input voltage is smaller, the initial error generated. This error can be corrected by ADC zero to eliminate.4. AD623 gain bandwidth of 800KHZ, namely the gain multiplier * Frequency = 800KHZ. Therefore, if the DC signal amplification, up to about 1000 times. If you zoom 1KHZ AC signal can be enlarged 800 times. If you zoom 10KHZ AC signal can be enlarged 80 times, and so on.5. REF side maximum adjustment range is + - (VCC-1.5V), such as 3V supply, the maximum can be adjusted within a range of plus or minus 1.5V, 5V power supply can be adjusted up within plus or minus 3.5V. This range is not unlimited.6. AD623 is a differential amplifier that can signal and the op amp is not common ground, but some buyers debugging is not good, if not special needs, it is recommended to use common ground.Sixth: Wiring (as photo shows) ( ---☆ ayanhu81 shop welcome you to buy it ☆---) Package included:1x Microvolt/Millivolt Voltage Amplifier AD623 Module (as first photo shows) response > We maintain hightest buyer ratings > Positive response will be much appreciated from you.> Any dissatisfaction, please contact us immediately!> Please do not leave neutral or negative response before we help you out.
