General Description
The TPA8304 is a logarithmic detector optimized for the measurement of low frequency signal power in fiber optic systems and offers a large dynamic range.
Wide measurement range, accuracy and fast step response are achieved, which is very suitable for the requirement of optic system.
Key Features
- 7 full decades of range: 1nA to 10mA.
- Law conformance error: 0.2 dB from 10nA to 10mA.
- Fast step response: raising 0.2μs, falling 5μs for 10nA to 10μA input on INPT.
- Basic logarithmic intercept at 100 pA.
- Logarithmic slope of 200 mV/20dB (at the VLOG pin).
- Optimized for fiber optic photodiode interfacing.
- Single-supply operation: 4.5 V to 5.5 V.
- Power down mode.
