General Description  
Features  
The DS3920 precision current mirror is designed for ava-  
lanche photodiode (APD) and PIN photodiode biasing  
and monitoring applications. The device offers a current  
clamp to limit current through the APD and a current mir-  
ror output that produces a signal proportional (5:1) to the  
APD current. A diode is also provided to limit the voltage  
at the current mirror output.  
S Wide Voltage Input Range: 2.97V to 76V  
S Current Monitor  
Wide 250nA to 2mA Range  
5:1 Mirror Ratio  
Fast 50ns Time Constant  
S Current Clamp (2.9mA or 20mA, typ)  
S Voltage Clamp Protects Subsequent Output Circuitry  
S 6-Pin SOT23 (MAX4007 Compatible)  
The device accepts a +2.97V to +76V current mirror  
supply voltage. Internal current limiting (2.9mA or 20mA,  
typ) protects the monitored device from a short circuit to  
ground. The provided internal clamp diode protects the  
current mirror output from overvoltage. Additionally, the  
device features thermal shutdown if the die temperature  
reaches +150NC.  
Applications  
Avalanche Photodiode (APD) Biasing  
PIN Photodiode Monitoring  
GEPON, GPON, 10GEPON, XGPON: ONU and OLT  
The device is available in a 6-pin SOT23 package, and  
operates over the -40NC to +85NC extended temperature  
range.
