Hi Henry,
Please see below for modification to the input circuit while driving the THS770006 in single-ended to differential configuration from a 50-ohm source.
If you are driving the device with a 50-ohm source, then it is not necessary to have the…
Part Number: ADS5263EVM Other Parts Discussed in Thread: THS770006 , ADS5263 Hello, I have a question about Vcm in ADS5263EVM. In datasheet for ADS5263 I see the recommended common-mode voltage = +1.5V (+-50mV), and for THS770006 this voltage needs to…
Hello Ed,
On the ADS5263EVM, it follows the schematics (on User’s Guide):
The footprints of 4 channels can be used for transformer or THS770006.
But due to the components limitation,
the EVM was soldered according to Default configuration:
1…
Hello Boniello,
How are you?
Thank you for using our ADS5263 device.
Please take a look at TI ADS5263 User's Guide as the following link:

On its page 5 and page 6 (also you can test on ADS5263 EVM's CH_IN3A…
Hi Carlos,
We've given example driving circuit using THS770006 op-amp in the user guide of ADS5263 EVM. You can use similar configuration in your application. I'm adding the reference below,

Please refer to…
Hi Chris,
The ADS5263 cannot sample DC signals in its default configuration. Channels 1, 2, and 4 are limited by the transformers to input signals above 400kHz. Channel 3 is limited by the ADC driver's (THS770006) output common mode voltage range. The…

Hi Niels,
A big challenge is the swing close to ground {0.95V(CM) - 0.5(peak_swing)V= 0.45V from ground} when using a DC coupled Fully Differential Amplifier (FDA) for this purpose, while maintaining low distortion at high frequency in the 10's of MHz…
