Product Description
The OE4101 is a transimpedance current pre-amplifier that utilizes a negative feedback structure to convert input current to voltage using a feedback resistor and to control amplification.
The OE4102 detects current by measuring the voltage drop across a resistor on the input current channel, amplifies and outputs a voltage signal proportional to the measured current.
