ADS58J63: Analog Input Model for ADS58J63

Kiran VG

Part Number: ADS58J63

Hi,

I am using ADS58J63 in my designs. I want to design analog input impedance matching network as per my requirement. Hence is there any models available for Analog Input pins of this ADC? If yes please share it with me.

Regards,

Kiran V.G.

Hi Kiran,

There are not any available models for the analog input.

Hi Dan,

Is there any input impedance equivalent lumped element circuit at any frequency which I can replicate and use in my simulation.

Kiran,

What is the range of your input frequency? For 370MHz, the datasheet gives equivalent input resistance (500 Ohms) and capacitance (2.5pF), which can be used to design a matching network.

Hi Jim,

I am interested in 250MHz - 500MHz frequency range.

Kiran,

Sorry, but the only information available is what is in the data sheet.
