THS4532: Looking at the above circuit design is reasonable?

Lian Wu

Part Number: THS4532

Dears:

Customer wants to use THS4532 to realize single signal to differential signal. In the below figure, A is a sinusoidal signal with a midpoint of 2.5V peak-to-peak value of 300MV. A+, A- want to get a differential signal with a midpoint of 2.5V peak-to-peak value of 1V. Please help us. Looking at the above circuit design is reasonable?

Is the THS4532 selection reasonable and is there a more suitable chip? Need 2 differential amplifiers.

Hi Lian,

figure 98 of datasheet shows how to proceed.

Hi Luck,

Did this resolve your issue? Please indicate. Your circuit is unbalanced. R1 should be 0 ohms and R13 and R14 should be 604 ohms for a 2.5V reference with a Thevinin equivalent to the 302 ohms on the other side.

Best regards,

Sean
