• ### RE: AD9265 cmos clock driver

My signal is IF signal at 10.7MHz, which can go -50dBm to 0 dBm.

to convert single ended to differential i am planning to use ADA4938.

• ### RE: Can I use ADA4938 as a differential driver and receiver?

Hello John,

I am trying to use ADA4938 as a differential driver for transferring signal from board to board (DC coupling through SMA cable). I am wondering what is the output impedance of ADA4938 when it's configured as a DC coupling differential driver…

• ### Simulation Problem of ADA4938-1

Dear Emman.A,

I want to use ada4938-1 to drive the ADC ad9629, before we start the design,  I do the simulation of ada4938-1, but I met some problems when I do the simulation.

the steps of simulation:

First , I get…

• ### Does the voltage of pin Vocm influence the gain of ADA4938?

Hi ,

I use the ADA4938 to Drive the ADC(AD9629), the pin Vocm connected to pin VCM of AD9629, and the output voltage of pin VCM is MID AVDD Supply (0.9V).

The schematic is shown below, and the gain of ADA4938 should be 0.5 in theory.

When the…

• ### Need recommendation for a dual supply converter solution for ada4938.

Does any ony know of a supply solution for +/-5 volt dual supply for noise sensitive ada4938 analog front end application?

Application includes 18 total ADA4938's that need+/-5V.

Any help is much appreciated.

Thanks.

• ### ADA4938 not static CMRR at low frequencies

We are reevaluating the use of the ADA4938. The CMRR is specified to be TYP: -75dB @ ∆VIN, cm = ±1 V, f = 1 MHz.

The CMRR measured on an Eval Board with ADA4938 reveals, that the CMRR is strongly frequency dependent. (red curve: ADA4938, blue: ADA4932…

• ### RE: how to reconcile the capacitive sensor with a close differential amplifier?

• Hi Jino,
• there is capacitive sensor that gives a signal in the frequency band 0-500mHz. I want to be placed in it close proximity amplifier (ada4927 or ada4817or ada4938 or ada 4939) amplifier with a gain of 1-2 and hand it to an oscilloscope. How…
• ### ADIsimPE How do I define the correct symbol?

Hi, all.

So I imported ADA4938-2's spice model and define the symbol,

ADIsimPE doesn't show the correct symbol.

How do I define the correct symbol?
