Datasheet
SMPX500 Series of Hybrid Detectors
The SMPX500 series is a range of integrated photodiode amplifiers incorporating a 1.75mm² silicon
PIN photodiode, operational amplifier and transimpedance circuitry. The devices provide a voltage
output proportional to incident light.
Features
Incorporation of the photodiode and amplifier into a welded metal can minimises noise pickup,
leakage current errors and stray capacitance normally associated with discrete designs. Gain and
bandwidth options are available to suit a wide range of applications and the devices can be operated
from single or dual rail supplies. Lens or Flat window can versions are available to suit the
application, as well as optical filters to minimise unwanted signals.
Applications
These devices are especially suited to low-light level
or applications where high sensitivity is required:
