9 / 11 page 6 9 ® OPT301 FIGURE 5. “T” Feedback Network. FIGURE 7. Differential Light Measurement. FIGURE 8. Current Output Circuit. Bandwidth is reduced to 2.8kHz due to additional photodiode capacitance. FIGURE 6. Summing Output of Two OPT301s. 1M Ω OPT301 40pF 75 Ω 2 83 5 4 1 V– λ V+ R 1 19k Ω R F R 2 1k Ω V O = I D RF R 1 + R2 R 2 Advantages: High gain with low resistor values. Less sensitive to circuit board leakage. Disadvantage: Higher offset and noise than by using high value for R F. 1M Ω OPT301 40pF 75 Ω 2 83 5 4 1 R 1 1k Ω –15V λ +15V R F I D I O ≤ 5mA I O = ID 1 + R F R 1 1M Ω OPT301 40pF 75 Ω 2 83 5 4 1 NC λ R F 1M Ω OPT301 40pF 75 Ω 2 83 5 4 1 V O V– λ V+ R F 8 This OPT301 used as photodiode, only.
