N/A
The AZ3267 is a transimpedance amplifier for 2.5Gbps fiber optic receivers. The part operates from a single
3.0V to 3.6V or 4.5V to 5.5V supply. Photodiode bias is provided via a 1.5kΩ resistor from VCC.
DC restoration is built in, with no external compensation capacitor required. The DC restoration can be disabled
for testing by pulling the FILTER pin to ground potential.
If the part is operated using the VCC5 supply pin, the VCC pin should be bypassed to ground with a capacitor of at
least 0.1µf.
