AD8145 & AD8146 Allegro File

To set the gain of 1 or 2, either i should ground gain_x pin or gain_x pin to out_x.. Kindly let me know the characteristic impedance of the trace between Gain_x pin to Out_x,

if my output is 75 Ohm.

Hi,

   Please refer reference schematic at AD8143-AD8145_Customer_Eval_Board_Schematic.pdf .

  Also refer this thread AD8145 Reference Schematics Required - Q&A - Video - EngineerZone (analog.com) here expert given some suggestion w.r.t AD8145 hardware specific related things.

   As per specification, AD8145 can be configured for a differential-to-single-ended gain of 1 or 2 by connecting the GAIN_x pin of each channel to its respective output (G = 1) or connecting it to a reference voltage (G = 2), which is normally grounded.

Thanks,

Poornima

Kindly share the PCB Board File of AD8145 and AD8146. Atleast share the gerber file of same IC family.

The eval board user guide can be found here.

For custom layout just follow standard 50 Ohm PCB layout guidelines.  If need be we can review the layout.

Here are the gerber files

Thanks Guenter, for sharing the Gerber files!!!
