Part Number: OPA2381
Other Parts Discussed in Thread: OPA381,
Hello E2E Experts,
The datasheet of OPA2381 majorly explains about OPA381 and then OPA2381 being dual. The block diagram about OPA381 shows Zero-drift in the Non-Inverting Input path.
Do Zero-drift circuits separatly exist for each Non-Inverting of OPA2381 also ? I tried to use OPA2381 as per schematic on page 1 of datasheet with RF = 1M.
The photo-diode is reverse connected and OPA2381 on Unipolar 5V Supply. When light level on photo diode is changed form darke to light or bright light, there seems no change in the output voltage at pin 1 or 7 of OPA2381.
