Hello,
I have a customer asking for the design package of the eval board for the AD9235, gerber files, schematics, etc.
Can you provide?
Thanks,
Anita
Let me confirm how to set up AD9235 (12bit AD Conveter) with AD8132(Differential Amp.).
My question is the relation between SENSE, VREF in AD9235 and VCOM in AD8132.
In my understanding, VREF can be connected with external voltage as an input.
So…
Hi
Could you give me any advice as below?
I have been designing PCB using AD9235 and AD8132.
I have designed AD8132 using input signal impedance matching as 50ohms to get differential output.
My question is to confirm the connection between…
Could you please advise me the minimum input frequency of AD9235 without an influence of external capacitor? I would like to use AD9235 by wide frequency range.
And how about the AD9649 and AD9266? Is it same as AD9235?
Best regards,
Akira
Hi,
I have a question inner circuit for AD9235 .
I woukld like to know inner sample hold time for AD9235-20,-40,-65.
My customer wants to know it,
So if you like , Please tell me sample hold time..
Best regards

In the datasheet of the AD9235 there is a specification for gain drift when using an external reference.
is there any data available regarding typical gain drift when using the internal reference?

Im using AD9235-20 in single-ended configuration with 1V applied to Vin-.The power supply of AVDD and DRVDD were both 3.3V.And the clk was drived by a 10.000Mhz-crystal-controlled oscillator.
The testing source came from a regulated power supply.The…
I wonder what communication method (i2c, UART, SPI) does AD9235 use and which pin is for communication. And if I want to achieve full 20MSPS, what is the minimum frequency of CLK source. Is Arduino Uno R3 powerful/fast enough to communicate with AD9235…
请教ADI工程师,我想用AD9235-65芯片,我的输入信号频率50K左右,输入信号经过滤波后,离AD9235的距离很近,是不是就不需要单端转差分输入了?我的信号本来是单端的。或者更进一步,在什么情况下才需要单端转差分信号?谢谢!
According to AD9235 datasheet. There are 2 type of input circuit.
On page 16, Figure 35, AD8138 Positive output go to AD9235 VIN+, negative one go to VIN-.
On the other hand, page 23, Figure 46 shows analog input circuit on AD9235 EVM that…
