Hi All, what is the input type for TS321ILT? Is it Rail to Rail or Differential input?

Welcome, @Venu Busani​, to the community!

Even though the LM321 TS321 is an improved version of the LM324 the LM321 is still neither rail-to-rail input nor rail-to-rail output.

The point about differential input is unclear: what do you mean by that?

[edited: sorry, mixed up LM321 and TS321, see statement below]

Hi Peter,

What is the input voltage type?

Input voltage range?

Sorry, I had confused the TS321 with the LM321 in my previous statement.

The TS321 is indeed not an opamp with RRIO, but needs some distance especially to VCC to work correctly. The input common mode voltage range is given in the datasheet for VCC=30V and has for the whole temperature range from 0...VCC-2V.

The safety margin of 2V will be slightly larger with smaller VCC, but is not part of the guaranteed parameters.

The values for the output voltage can be found together with the environmental conditions in the data sheet, table 3.

The datasheet instantly answers all of those questions. If you cannot see those answers, it means you do not even understand the terms, which you are asking.
