*1: Custom types for multi-element detectors are also available.
*2: When connected to a detector, frequency response becomes 60 kHz or less depending on the detector active area. (φ0.6 mm: 60 kHz or
less, φ1 mm: 25 kHz or less) Ringing occurs in the output if the rise time tr (0 to 90 %) of incident light is approximately 100 μs or less.
The ringing becomes larger as the rise time becomes shorter. No ringing occurs when detecting sine-wave light. (For information on the
ringing specifi cations, see page 2.)
*3: Recommended DC power supply (analog power supply): ±15 V
Current capacity: More than 1.5 times the maximum current consumption
Ripple noise: 5 mVp-p or less
Note: Output noise voltage = Equivalent input noise current × Conversion impedance
For information about accessories except for the amplifi ers, refer to our datasheet “Infrared detector accessories”.
