Typical applicaTions Single Supply Hi-Gain 80kHz Photodiode Amplifier
3V R2 1k *CP = SUM OF PHOTODIODE CAPACITANCE, PARASITIC LAYOUT R3 C1 R1 3V CAPACITANCE AND LT1797 INPUT CAPACITANCE ≅10pF. 10k 0.1µF 100k + R6 TRANSIMPEDANCE GAIN: AZ = 10MΩ. 330Ω PHOTODIODE LT1797 R6, C3 LIMIT THE NOISE BANDWIDTH TO 500kHz. C SFH213FA P* – C3 1000pF OUTPUT NOISE ≅1.8mVRMS. R1, CP AND LT1797 GBW SET UPPER LIMIT ON BANDWIDTH. R4, C2 SET LOWER 1.6kHz LIMIT ON GAIN OF 101. R4 R5 1k 100k C2 0.1µF 1797 TA02 1797fc 10 For more information www.linear.com/LT1797
