THS2630: THS2630SDR

Ravi Kumar Vasireddy

Part Number: THS2630

Tool/software:

We designed single ended to differential conversion for ADC input using THS2630. we are getting the output +/-10V even input we are changing the input. what could be the problem.

Hello Ravi,

Can you confirm your input test signal? Can you also confirm the quiescent (operating) current of the THS2630 if you are measuring on bench with a PCB?

Best,

Alec

Input test signal from DAC output +/-10V, quiescent (operating) current of the THS2630: +12V (57mA), -12V (64mA)

Hello Ravi,

What is the signal frequency of your input waveform?

Does the output behavior improve if you add more resistance to the output, such as replacing C72 with a 1kOhm resistor?

Are the feedback capacitors sized correctly? Why was 100nF selected?

Best,

Alec
