I am working on a signal conditioning project in which i am using opa348. but i am working on a general purpose PCB. So, it is difficult to solder the SMD IC. So, is there any PDIP IC available equivalent to opa348.

Hi Vishal,
I searched for some electrically similar operational amplifiers to the OPA348 that are available in the PDIP package. I used the PDIP package availability and OPA348's 45 uA supply current as the leading criteria, supply voltage range and rail-to-rail I/O as follow-ups.
Take a look at the OPA347, OPA336 and TLV2451.

Check and make sure that their dc and ac specifications meet your applications requirements.

Vishal,
I am not sure what you mean by SMD IC; OPA348 is offered in three packages: SOT23-5, SC70-5 and the largest SO-8 - please see below.
No two parts are identical and you do not specify what are your most important specs in your application; so here are some op amps offered in PDIP package with spec 'similar' to OPA348: OPA337, OPA340, OPA343, OPA344.
Sir,
I want signal conditioning of the signal coming from CT (current transformer or current transducer). The output of the CT is an AC signal and i want to shift the signal above zero level by providing some dc bias.
example: Assume that range of the output signal of CT is +1 V to -1 V, then i'll provide dc bias of 1 V. So, that the range becomes +2 V to 0 V. The main purpose is to shift the level above zero.
Please suggest suitable op-amp (which have PDIP package) for this purpose.
Vishal,
For the DC level shift you may be required to use rail-to-rail input op amp; any of the following op amps is offered in PDIP package with rail-to rail input common-mode: OPA340, OPA343, OPA344, OPA347 and TLV2451. You may request free samples of some of the op amps to try them out in your application.
