Ideal for professional-grade instrumentation, this module supports negative voltage output and zero drift adjustment, making it perfect for sensitive small-signal applications in compact form factor. ## Description Description: High Precision uV / mV Voltage Amplifier Small Signal Instrumentation Amplifier AD620 Transmitter Using AD620 as the main amplifier, can amplify uV, mV voltage. Magnification 1.5-10000 magnification, adjustable. High precision, low offset, better linearity. Adjustable zero to improve accuracy. Can be used for AC, DC signal amplification. Module use, need to have a certain electronic basis, if no basis customers, please carefully purchase, shop to provide technical support. Product Highlights: 1: wide supply voltage range, the AD620 amplification of this product can be amplified microvolts, millivolt, compared to LM358 amplification accuracy, better linearity, the maximum voltage output range of ± 10V. 2: magnification range, magnification up to 1000 ti2mes, only through a potentiometer can be adjusted. 3: adjustable zero through the zero potentiometer to adjust the zero, improve accuracy, there will be no zero drift phenomenon to meet customer needs. 4: a negative voltage output, the module uses 7660A chip output negative voltage (-Vin), can be provided to the customer to drive other dual power load. 5: mini type, the size of 32 * 22mm, evenly distributed around the four 3mm positioning holes, both sides of the port 2.54mm standard pitch pinhole. Product parameters: Input voltage: 3-12VDC. magnification: 1.5-1000 times adjustable, zero adjustable Signal input voltage: 100uV - 300mV Signal output range: ± (Vin-2V) Negative voltage output: higher than -Vin. As the negative voltage chip output resistance problem, the actual output is higher than -Vin, the greater the load power, the greater the negative voltage drop. Offset voltage: 50μV. Input bias current: 1.0nA (max). Common mode rejection ratio: 100 dB Offset voltage drift: 0.6μV / ° (maximum). Stability: 2μV / month maximum Size: 32 * 22mm Weight: 4g Package Included: 3* Voltage Amplifier Transmitter Review: Works as described - Work fine converting the differential voltage from a pressure transducer into a single-ended voltage. I did not find it necessary to adjust the potentiometers. One nit-pick is that it would be helpful to have a V+ terminal on the input side of the PCBA. There are plenty of GND points but I needed V+ to flow through to excite my transducer. Review: Nice AD620 instrumentation amp, ready to go but build quality is poor. - Great little amp setup, but glad I bought 2. The surface mount components are very fragile and will pop off the board easily, so handle with extra care and build a box for it. Signal is good and pretty clean and the price is right. ## Features - High precision DC voltage signal amplifier module for microvolt /millivolt signal amplification with 1.5-1000 gain range adjustment - Equipped with AD620 instrumentation amplifier chip support ±10V(maximum) signal voltage output with high precision and good linearity better performance than LM358 - Support null point adjustment, negative voltage output and noise filtering capabilities ensure you can get the low distortion but high frequency signal ideal for small signal amplification - Input Voltage: DC 3-12V, Signal Input Voltage: 100uV-300mV, Module Size: 32 X 22mm/1.26 X 0.87inch(L*W) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08QM9SM1W | | Best Sellers Rank | #46,981 in Electronics ( See Top 100 in Electronics ) #257 in Audio Component Amplifiers | | Brand Name | Teyleten Robot | | Customer Reviews | 4.1 out of 5 stars 51 Reviews | | Item Dimensions | 1.26 x 0.87 x 0.07 inches | | Item dimensions L x W x H | 1.26 x 0.87 x 0.07 inches | | Manufacturer | Teyleten Robot | | Maximum Supply Voltage | 12 volts_of_direct_current | | Minimum Supply Voltage | 3 volts_of_direct_current | | Model | H64 | | Mounting Type | Through-Hole Mount | | Number of Channels | 1 | | Package Type Name | Individual Component Packaging | | Part Number | H64 | | Specification Met | General Specifications | | Supply Current | 1.2 milliamps | | UPC | 606592873307 | | Voltage | 12 volts_of_direct_current | ## Product Details - **Item dimensions L x W x H:** 1.26 x 0.87 x 0.07 inches - **Manufacturer:** Teyleten Robot - **Maximum Supply Voltage:** 12 volts_of_direct_current - **Minimum Supply Voltage:** 3 volts_of_direct_current - **Voltage:** 12 volts_of_direct_current ## Images ![Teyleten Robot Millivolt/Microvolt Voltage Amplifier AD620 Instrumentation Module DC 3-12V High Precision Signal Amplifier (3PCS) - Image 1](https://m.media-amazon.com/images/I/71l6HWV+MdL.jpg) ## Questions & Answers **Q: want to amplifiy a mV dc signal to V. Is s+/s- the +/- mV input and the +/- amplified signal across Vout/V-?** A: Yes, s+ and s- are the inputs and are differential Next to the s+ & s- inputs is the positive voltage to run the board V + 3.5 to 10 volts is fine this is fed to the internal DC to DC converter and is self regulating. The V- pin on the other side of the board is not used but you will find a negative voltage at that pin when V+ is fed to the board this voltage is internally generated by the DC to DC converter to provide differential swing to the output. You are correct the amplified output is across Vout and ground. The two trim pots one controls overall gain and the other controls DC balance or offset. Good luck with your project **Q: S= and s- are for the mv signal? and vout and v- are the output signal (in volts)? is the vin and gnd i.e. power supply +12v for amplifier?** A: s+ and s- are the inputs. Vin is about +12V and vout is the signal output. the v- is a negative supply generated onboard (the 620 chip has +/- power. Only a + supply is needed. v- can be left unconnected. **Q: How do you measure gain? Can you do it with a multimeter?** A: Yes that is how I did it. **Q: What is the range of the dc offset knob? the signal i need to amplify is offset 2.5 v.** A: Input voltage: 3-11VDC ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works as described *by M***N on April 4, 2023* Work fine converting the differential voltage from a pressure transducer into a single-ended voltage.
