Title: Instrumentation Amplifier AD623 Voltage Amplifier Module Adjustable Single Power Supply Single-ended/Differential Small Signal
Module model: 


Module type:  Weak signal amplifier
Input signal formation: single-ended or differential (disconnect SB5 jump point to be differential input) Input voltage range: 100uV-1Vpp
Module power supply voltage: DC6.5V-26V Module power supply current:  20mA
Output voltage range:  ±5V (MAX) Output current:  10mA (MAX)
Module gain range: 1-10000 times (adjustable sliding) Gain control method:  program control/slip change (jump cap switch)
Program control protocol:  SPI (8-bit digital potentiometer) Bias voltage adjustment range: ±2V (MAX)
Input offset voltage:  200uV (MAX) Input offset drift:  2uV/℃(MAX)
Input bias current:  125mA (MAX) Common mode rejection ratio: 90dB (MIN, G=10)
Input voltage noise:  35nV √Hz Module protection:  Yes (diode anti-reverse protection)
Module weight:  16g Module specifications:  50x50x7mm
Module heats up: no heat sink (excessive input voltage may heat up) Module heating factor: the input voltage is too large or the module is damaged
Module working temperature: -40℃ - +75℃ (industrial grade) Module features: output power LED indication, output 5V linear power
Precautions for module use: (1) The power supply of the module is a dual power supply, and the voltage cannot exceed ±15V
(2) Since the module is a high-precision device, for your unnecessary interference, it is recommended to use a linear power supply
(3) For the output signal, it is recommended to use a good wire for input and output signals, and use an oscilloscope to observe the effect.Poor contact or poor quality wire may cause signal attenuation or excessive noise.
Frequently Asked Questions:
Q: How to adjust zero when the module is single-ended input?
A: The module defaults to a single-ended input. After IN+ is grounded with a resistor, the offset can be adjusted to zero, or the input signal can be adjusted to zero by adjusting R6.
Q: The module is single-ended by default. What should I do if I need to input a differential signal?
A: When you need to input a differential signal, you first need to remove the jumper cap, then remove the R6 potentiometer, the differential input bias cannot be adjusted, and then use IN+ and IN- to input.
Q; What happens when the gain potentiometer is welded and there is no response when adjusting the gain of the potentiometer?
A: The module has a default magnification. The soldered potentiometer and the default resistance R2 are connected in parallel. First of all, the potentiometer is multi-turn and needs to be adjusted a few more turns, or the adjustment is more sensitive after removing the R2 resistance.
