AD623 Voltage Amplifier Module, Mini Module Adjustable Instrumentation Amplifier, Differential Amplifier Single-Ended/Differential Small, Module

【Module Power Supply】5V-24V Is Ok, But It Depends On The Output Of The Baby Distribution Voltage (if The Customer Requires The Output 5v Voltage, Then The Ad62x Series Chip Is About ± 3.8v Power Supply, The Voltage Difference Of Its Own Voltage Stabilizer Chip, So It Is Recommended To Be Higher Than 12v Single Power Supply Is Better).
【Better One】AD623 is better than AD620 in practical use. AD623 can use single power supply, belonging to rail-to-rail operational amplifier, but the power supply range of AD623 (± 6v@maxium) is much smaller than that of AD620(± 18v@maxium); the internal bias of AD623 is much smaller than that of AD620. when we debugged the module, you did not need to adjust the bias, the ac signal is basically symmetric relative to the 0 point.
【Application】The AD620 is a low-cost, high-precision instrument amplifier that requires only an external resistor to set the gain, which ranges from 1 to 10000. This module can be enlarged 1000 times, with neat circuit layout, MINI, reasonable design layout and wiring, generous materials, suitable for project development and student competition.
【Sugggestion】The Maximum Amplification Factor Of The Module Is More Than 2000 Times (measured). As The Gain Assembly Leads To Large Fluctuation In The Waveform Band, It Is Recommended To Adopt Multi-stage Amplification For High Gain.
【Lastest Type】The latest two AD620, for a fixed gain version (with metal shielding cover), or for adjustable gain version (without metal shielding cover), the two have a fixed voltage output all the way, sliding variable in the shipment without welding, but with shielding cover + sliding variable, the user can choose according to their own needs.
