SPECIFICATION

• AMP01 Micro Signal Amplifier Instructions
• Isolated small signal amplification module, carefully designed with industrial-grade high-quality components, default amplification
• 20-1000 times. Adopt AD620 and isolated power supply design, with two-stage amplification and multi-stage filtering at the same time, with strong anti-interference
• Ability, the module has the characteristics of high stability, high precision, and low offset.
• One: functional characteristics
• 1. The design of isolated power supply is adopted to realize a single power supply of 5-30V, and it can provide 12V/20m power output for users.
• 2. Module power consumption is less than 0.3W: 39mA at 5V, 19mA at 12V, 10mA at 24V.
• 3. The module can be used for uV or mV signal amplification, with high accuracy, good linearity, and linear output range from -10 to + 10V.
• 4. The default magnification of the module is 20-1000 times adjustable, and users with special needs can customize 2-1000 times the module.
• 5. With zero point adjustment function, the adjustment range is -2.5V to +2.5V. .
• 6. The module has built-in multiple filters, which can effectively filter out high-frequency interference signals and ensure signal stability. The default bandwidth is about 2000Hz2.
• 7. With power indicator light, the blue light is on when connected to the power source.
• 7. DC characteristics (AD620):
• The maximum input offset voltage is 50uV.
• Maximum input offset drift: 0.6μV/C.
• Maximum input bias current: 1.0nA.
• Minimum mode rejection ratio: 100dB (minimum value, G=10).
• Input voltage noise: 9nV/ VHz.
• 8. Size: 55mm*35me* 15mm (length*width*height), with 4 3me screw holes reserved.
• 2: Description of terminal
• Left terminal
• 1. DC+: Power input positive (input range DC5- 30V, with anti-reverse protection).
• 2. DC-: negative pole of power supply.
• 3. V+: Positive 12V output, output capacity +12V/20mA.
• 4. GND: signal ground (earth 12V power ground), isolated from input power
• 5.V-: negative 12V output, output capacity -12V/20mA.
• Right terminal
• 1.St: signal input positive
• 2.S-: signal ground
• 3.S-: signal input negative
• 4.OUT: Amplified signal output terminal
• 5. GND: signal ground
• Three: electrical parameters.
• Working voltage: DC 5-30V
• Working current: 39mA at 05V.
• 19mA at 12V
• 10mA at 24V
• Working temperature:-30C- 60C (limit range 40C- -70C)
• Four: zero adjustment method
• You need to adjust the zero before use. The steps of zero adjustment are as follows (note: the position of the terminal in the figure may not match the actual object, please connect
• Pay attention to the terminal identification)
• 1. Short the input positive (S+) input negative (S-) and GND, as shown in the figure below.
• 2. Turn the gain appliance clockwise to adjust the gain to the maximum.
• 3. Rotate the zero point electrical appliance to make the signal output port OV.
