Products Information
Ultra-highly Sensitive, Super Compact, but Ultra-low Price Galvanometer Amplifier for Use in Picoampere Measurements
I / V Converter (1G) T-IVA001S
With a skillful circuit design and intelligent selection of the parts used, the product was designed to be compact but of high performance at a low price.
Utilizes a low input bias operational amplifier and high-precision resistor. For use in very accurately converting ultra-low current at the picoampere level into voltage. Supports a direct current power supply, and thus boasts a high SN ratio. Use of batteries as the power supply enables further reductions in the noise level. The input is appropriately protected, thus eliminating any concern.
