1. Exquisite module, excellent magnification performance.
2. The weak detection effect is good.
3. 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@) is much smaller than that of AD620(± 18v@), so AD623 is more suitable for integration in low-power and low-voltage applications.
4. Secondly, the internal bias of AD623 is indeed much smaller than that of AD620. When we actually debugged the module, we found that AD623 basically did not need to adjust the bias. The ac is basically symmetric relative to the point, but the AD620 needs to adjust the special bias circuit to eliminate the dc component and achieve the effect of point symmetry.
5. Finally, the bandwidth of AD623 is different from that of AD620, and the bandwidth of AD620 is slightly wider than that of AD623.

Spec:
Condition: Brand New
Item Type: Voltage Amplifier Module
Material: Metal
Color: As Pictures Shown
Module Size: Approx. 50x50mm/2.0x2.0in
Weight: Approx. 35g
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 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).
Module Bandwidth: At High Gain, AD620/623 Lower Than 50khz, And At Low Gain, Ad620/623 Is Greater Than 1mhz
Module Input Type: Single-ended Or Differential
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.
Module Saturation Output Amplitude: Ac Is 10vpp (±5vpp)
Fixed Output Voltage: 5v-10v (default Shipment: 5v)
