Supply +VCC pin with a voltage between 5.5 V and 12 V. Supply -VCC pin with a voltage between -12 V and -5.5 V. The board is regulated to ±5 V internally. Using more than ±6 V supplies increases power consumption without any significant improvement in supply noise rejection.
Supply the photodetectors with a maximum 1.5 mW optical power. The linear output voltage range of the transimpedance amplifier is between -3 V and 3 V.
The output is available on the SMA connector (50 Ω impedance).
