Driver circuit for InGaAs linear image sensor Driver circuit for InGaAs linear image sensor (G9494 series) C10820 www.hamamatsu.com The C10820 is a driver circuit designed for the G9494 series high-speed InGaAs linear image sensors. The C10820 generates clock signal and reset signal needed to drive the InGaAs linear image sensor, and ampli fi es and outputs the video signal of the InGaAs linear image sensor while subtracting the offset from the video signal. Features Applications Simple signal input operation (only digital signal inputs for START and M-CLK pulses, and +5 V and +15 V power sup- plies required) High gain setting suitable for low-level-light Compact size Absolute maximum ratings (Ta=25 °C) Specifi cations (Ta=25 °C) Parameter Symbol Value Unit Analog supply voltage +VA +18 V -VA -18 V Digital supply voltage +VD +7 V Digital input voltage - +VD V Operating temperature*1 Topr 0 to +50 °C Storage temperature*1 Tstg -20 to +70 °C *1: No condensation Parameter Symbol Min.

When used with the G9494-512D, M-CLK is divided by 2, and CLK-ODD and CLK-EVEN are generated with complementary timing and output while each is shifted by half the CLK period. This means that the G9494-256D and 9494-512D operate at the same data rate when a same frequency M-CLK is input.

The active area of the InGaAs linear image sensor must be light-shielded during this adjustment. Turn the trimmer clockwise to increase the offset, or turn it counterclockwise to reduce the offset. In either case, adjust the offset so that the VIDEO signal becomes higher than GND. O Circuit gain adjustment: VR2 Use the VR2 trimmer to adjust the circuit gain according to the incident light level. Turn the trimmer clockwise to increase the gain, or turn it counterclockwise to reduce the gain. Note that the DC offset also varies when the gain is changed by VR2, so readjustment to the circuit DC offset might be required. O Sensor gain selection: SW3 The integration amplifi ers in the InGaAs linear image sensor have a function to select the integration capacitance (Cf). This selection is done by SW3 on the driver circuit. Switching SW3 to the left side selects the low gain, and switching it to the right side selects the high gain. The high gain is approx. 8 times higher than the low gain. Please note that the VIDEO signal from the driver circuit becomes saturated at approx. 4 V. Adjustment methods
