Photo-ICs result from the pairing of a photodiode and an integrated-circuit amplifier resulting in substantial light currents and response well into the megahertz range, and beyond. They have become the favored sensor for many applications that require photodiode response with larger outputs – well into the tens of milliamps. Devices are available as buffers or inverters; some include a gain control terminal to allow the customer to control the device sensitivity.
Additionally, for higher-volume applications, ASICs can be designed and tooled to make an IC sensor uniquely-tailored to your specific requirement. Contact Clairex for assistance with your photo-IC requirements.

Notes:
- Click on part number for datasheet.
- 7:1 user accessible gain adjustment.
- Acceptance angle at half power point.
- W suffix indicates flat window.
Definitions:
- Ee+is the minimum irradiance required to cause the output to change state.
- Buffer; Output is HIGH when input irradiance is > Ee+.
- Inverter; Output is LOW when input irradiance is > Ee+.
- Vcc range; 4.5 volts to 16 volts.
- Icc maximum is 25mA at Vcc = 16 volts.
- The gain of the photoIC sensors is thermally compensated to the temperature coefficient of an average AlGaAs (880nm) IRED.
