Hi,
I have a problem with the OPA3S2859-EP (Programmable Gain Transimpedance Amplifier) device.
The configuration used is the one shown in the figure where:
Vin=+5V
-Vbias=-5V
Supply voltage (VS+ - VS-)= 5V - 0V
Output at 50 ohms.
SEL1, SEL0, LATCHA, LATCHB are configurable via pins.
The photodiode used is the Thorlabs FGA01FC.
The output signal without an optical signal is 100mV. I have an offset of 100mV.
The amplifier saturates at about 600mV.
Shouldn't the output signal be between 0 and Vs-0.5? Why the output saturates at 600mV?
Thanks
Nicola
