AD620 High precision millivolt microvolt small signal differential voltage Instrumentation amplifier weak signal module AD623

Advantages of this product:

1: Wide input range: This product adopts AD620 amplification, which can amplify microvolts and millivolts, with higher accuracy and better linearity than LM358 on the market.

2: The Potentiometer is used to amplify the input signal, and the amplification is up to 1000 times. Only one Potentiometer is needed to adjust the amplification (10-1000 times are adjustable by default, and customer service needs to be contacted below 10 times).

3: Wide power supply range with input of 5-30V DC power supply

4: The size of the ultra mini model is 50 * 29mm, with four 3mm positioning holes evenly distributed around it, and the spacing between the positioning holes is 45 * 24mm; The outer distance between the two sides of the array is 1.7mm.

Ultra low Input offset voltage: 50 μ V.

Ultra low input bias current: 1.0nA (maximum).

Common-mode rejection ratio: 100dB

Ultra low Input offset voltage drift: 0.6 μ V/℃ (maximum).

Super stable, time: 2 μ V/month maximum
