Precision Switched Integrator Transimpedance Amplifier

Precision Switched Integrator Transimpedance Amplifier

This project is based on IVC102 chip from Texas Instruments. This chip is a precision integrating amplifier with FET OPAMP, integrating capacitors, and low leakage FET switches. It integrates low-level input current for a user-determined period, storing the resulting voltage on the...

Photo Diode Amplifier

Photo Diode Amplifier

This small module is a photodiode amplifier. The circuit consists of an OPAMP configured as a transimpedance amplifier for amplifying the light-dependent current of the photodiode. A small bias voltage is derived from the positive supply and applied to the op amp’s non-inverting...

Photodiode Amplifier for Visible Light Using OPA381 – Arduino Nano Shield

Photodiode Amplifier for Visible Light Using OPA381 – Arduino Nano Shield

The project presented here is a photodiode amplifier for visible light. The output voltage of the circuit increases linearly with light intensity. Low-cost BPW34 photodiode is used as a light sensor and OPA381 op-amp as an amplifier. OPA381 is a transimpedance amplifier that converts...
