IR101１Evaluation Board Manual Features • The evaluation board for AsahiKasei’s infrared sensor IR1011 including Current-Voltage convertor and amplifier. • Field of view (FOV) limiter and optical filter (5um long-pass filter) are mounted to make easy to start to evaluate. • Sensor output can be easily monitored by Current-Voltage convertor and amplifier. • IR1011 and the thermistor for temperature monitoring are mounted on the backside of other electronic components. • Dual Zero Drift Op-amp AK2920 is used for the amplifier taking advantage of the low offset and low drift features. Recommended Operational voltage 5.0 V( for AK2920 2.7V ~ 5.5V) Board dimension 10.0mm×14.0mm Current-Voltage conversion resistance 1MΩ Amplifier gain × 1000 Appearance Fig.1 Sensor Mounting Side Fig.2 Sensor Mounting Side (w/ FOV limiter and Filter) (w/o FOV limiter and filter) (Rev.A Ver.1.0)GS5A Fig.3 Component Side 2013/04 - 1/4 - Pins Connector J1 Pin Name Pin number Connection VCC 1 5V Supply GND 2 GND VOUT1 3 IR sensor output V UT2 4 Thermistor output J1 1234 Fig.4 Photo with connector Circuit Diagram IR sensor 4 NC1 P NC2 N Vref 1 2 R3 - + 7 - AK2920 VOUT1 6 1kΩ AK2920 4 3 Vref U1B 5 + 4 2 U1A 3 Vref 1 VCC 8 8 VCC GND GND R2 R4 1MΩ 1MΩ C4 10nF VCC VCC VCC R5 R7 10kΩ 10kΩ J1 Vref VOUT2 C6 R6 10kΩ GND C5 Rt1 C3 1uF 10KΩ 1uF GND GND GND VOUT1 VOUT2 1uF GND 1 2 3 4 GND Fig.5 Circuit diagram of the evaluation board • Roll-off is around 16Hz. • If the faster response is required, set C4 smaller.
