Hi! I wonder if there is a reference design schematic of MP4835.
Hi 22037796r,
Are you referring to the MP4835A | 32-Channel, High-Voltage Analog Switch with Output Bleed Resistors and 5V Bias | MPS (monolithicpower.com)?
If so, please reach out to MPS NOW Remote Support - Support (monolithicpower.com) and we can provide the DS for you.

Hi, thank you! Now, I have developed a board with MP4835, and you can see the pictures below. However, when I tested with signal generator as input to channe1 (connect the signal generator and oscilloscope to channel 1 and GND as marked in the picture), I found when the frequence of signal is larger than 10KHZ, the readings from oscilloscope would decrease. I wonder if there are any capacitors together with the switch-on resistors combining a RC filter that makes the attenuation. I wonder if there are any solutions for this problem?
Here are pictures of my layout and connections.
