pA Level Transimpedance Amplifier For Weak Current IV Conversion Preamplifier Dual Power Supply V2.0

pA Level Transimpedance Amplifier For Weak Current IV Conversion Preamplifier Dual Power Supply V2.0

Description:
The dual power supply version has input bias adjustment, and the feedback adopts a T type feedback network, and the output center point voltage is adjustable.

Features:
- TIA trans-impedance weak current measurement module; IV conversion preamplifier, pA-nA-mA for silicon light detection.
- Ultra-high-precision current measurement module, measuring range: 10pA to 2mA (limit parameter). It is suitable for rapid development and principle verification of personal projects. All have been measured by 6 and a half-digit instruments, including multimeter (DMM4050) and digital source meter (2363A).
- A typical trans-impedance IV circuit connection can achieve the most accurate current measurement in principle at the current level of technology.
- The main chip bias current is as low as 1pA, and the rail-to-rail op amp has high accuracy. The input voltage only needs to be positive (no negative voltage is required).
- Positive and negative current input version: It means that the input current can be positive or negative. Otherwise, you can only input the current according to the specified direction.
- This circuit has been improved several times, and the actual measurement is available and the performance is excellent.
- The output voltage Vout and input current I are calculated as: Vout = VCC / 2 ± I * R.
