Hi, I having trouble with two LMH6629 Eval boards.
Both units show either no output signal (for small input signal ~100mVpp, 10MHz) or a clipped waveform (for input signal ~1Vpp, 10MHz) .
I have set R10=0ohm and use single +5V supply.
I am using the standard non-inverting input. The current consumption is ~11mA;
The input and output impedance is ~50ohm;
The SW1A (PD) behaves as expected, powering down the device.
Here is the DC level I have measured with teh device powered ON and Idd~111mA
pin 1, PDZ: 5V
pin2, FB: 0.3V
pin 3, IN- : 0.02V
pin 4 , IN+ : 0V
pin 5, V- : 0V
pin 6, COMP: 5V
pin 7, OUT: 0.3V
pin 8, V+: 5V
Any idea what is going on?
