Product Number: MAX40213
Hi,
I've been playing with the MAX40213EVKIT which works ok in with transimpedance 150k but I cannot get a decent output with 750k transimpedance. It doesn't matter what I connect to its input (RF generator, floating, impedance to GND/3.3V...) it always oscillates with high frequency. Decoupling the power supply didn't seem to help either. Bot MAX40213 instances on the board behave the same, the circuit with 50Ohm outputs as well as the one with 1k termination and high impedance scope input.
Any suggestion how to get it to work in high gain mode is appreciated.
Best regards,
Daniel
