Description
The ADL5309 contains dual monolithic logarithmic transimpedance amplifiers that are optimized for measuring low-frequency and wide dynamic range optical signal power in fiber optic systems.
Features
- 188 dB electrical dynamic range and 94 dB optical dynamic range.
- Dual-channel current inputs for direct optical gain measurements.
- Accurately trimmed logarithmic response:.
- Logarithmic slope 200 mV/decade.
- Logarithmic conformance error ±0.4 dB over temperature.
- Offset trimmed at 70°C to reduce dark current.
- Integrated LDO: 26 dB PSRR at 60 Hz and 100 pA input current (VCC = 3.0 V).
- I2C adjustable:.
- Photodiode bias voltage.
- Trade-off between nois.
