Hello,

Our customer use the PSPICE model of the TLV171.

There is a " Syntax error " in subckt.

----------------------------------------------------------------------------------------

*
.subckt VCCS_EXT_LIM_TLV171 VIN+ VIN- IOUT- IOUT+ VP+ VP-
.param Gain = 1
G1 IOUT+ IOUT- VALUE={LIMIT(Gain*V(VIN+,VIN-),V(VP-,VIN-), V(VP+,VIN-))}
.ends VCCS_EXT_LIM_TLV171
*

---------------------------------------------------------------------------------------

Is there any wrong syntax description in this parameter?

Hello Tim,

Thank you for your reply.
The customer use" Altium Designer".
Does it need to change the syntax?

I tried to simulate in Tina-TI, there is no problem.

Hello,

I believe the issue your customer is facing with the TLV171 model is related to this forum thread. The TLV171 and the OPA188 both use the same model architecture so I am confident the issues are related.

Thank you,
