Part Number: THS4541
Tool/software: TINA-TI or Spice Models
Hi support team,
Our customer is considering THS4541 as a preamplifier of ADC input.
They are just starting simulation with TINA-TI.
Is there a simulation circuit for verifying the phase compensation of a fully differential amplifier like the THS4541?
I am not quite sure what you mean by "simulation circuit for verifying the phase compensation".
Are you referring to Open Loop Frequency Response that can be used to measure phase margin perhaps? or are you referring to closed loop configuration such as shown in this THS451 TINA-TI reference: http://www.ti.com/lit/tsc/sbom907 ?
Let us know
In reply to Herman Theodorus - WEBENCH Design Center:
Thank you for your reply.
I am glad to either reference circuit, but I want a reference simulation circuit especially for open loop frequency response characteristics.
I am unfamiliar with TINA-TI, so it is very helpful to have a simulation environment as it is.
In reply to Tomoaki Yoshida:
Thank you for the clarification.
Attached is the open loop test bench that you can use.

Thank you for your support.
It was very helpful for me.
