M02014
CMOS Transimpedance Amplifier with AGC for Fiber Optic
Networks up to 2.5 Gbps
The M02014 is a CMOS transimpedance amplifier with AGC. The AGC gives a wide dynamic range of 32 dB. The
high transimpedance gain of 11 kΩ ensures good sensitivity.
For optimum system performance, the M02014 die should be mounted with a photodetector inside a lensed
TO-Can or other optical sub-assembly.
The M02014 can either bias the PIN diode from the internal regulator or use an externally biased photodiode.
A replica of the average photodiode current is available at the MON pad for photo-alignment.
