Other Parts Discussed in Thread: TINA-TI
I tested D/S Fig.57 (Gain4) with TINA-TI.
If the output impedance of the differential signal source = 0 ohms, the output will be gain 4.
Our customer set the output impedance of the differential signal source to 100ohm as shown in Fig.57.
It may be natural, but the simulation will reduce the gain.
In the real case, their signal source is also 100ohm differential.
Is it okay to design the actual machine as shown in Fig.57?
The customer intends to change his Rg = 49.9ohm to 0ohm as the simulation will lower the Gain.
Since this method is different from normal design, could TI give me some advice?
