The M02016 is a CMOS transimpedance amplifier with AGC. The AGC gives a wide dynamic range of 35 dB. The
high transimpedance gain of 24 kΩ ensures good sensitivity.
For optimum system performance, the M02016 die should be mounted with a silicon or InGaAs PIN photo detector
inside a lensed TO-Can or other optical sub-assembly.
The M02016 can either bias the PIN diode from the internal regulator or use an externally biased PIN diode.
A replica of the average photodiode current is available at the MON pad for photo-alignment.
