ADC3244EVM: ADC3244EVM, single or dual input source?

Will Mitchell

Part Number: ADC3244EVM

I recently got hold of an ADC3244EVM and was looking to pair it with a TWS1400EVM in order to capture data for a project. On the TI website it is advertised as a dual channel Dev board but upon receiving it I noticed that there is only one SMA straight jack with which one can connect to an input source. In the schematics and data sheets it seems to suggest J3 and J4 both can take an input source. Is this actually possible and if some how would you go about doing this?

Will,

The board has options to input either a single-ended source or a differential source. By default, the board is setup for single-ended input source using SMA J1 for CHA and SMA J4 for CHB. If the user wanted to use a differential input, they would have to move some resistors and use SMA J1 and J2 for CHA and SMA J4 and J3 for CHB.

Regards,

Jim
