Avalanche-Photodiode Detector Circuit Limits Current to 1mA and Improves Transient Response
New, high-speed avalanche-photodiode (APD) detectors require new support circuits with lower current limits. This application note uses the MAX1932, a digitally-controlled, APD bias supply IC, to design an improved bias circuit for these new APD detectors. This circuit features enhancements to the standard MAX1932 application circuit.
