Need high input Impedance and low bias current Op Amp

Other Parts Discussed in Thread: LMC6061, LMC6001, OPA928

Hello Experts

Can you suggest any high impedance and low bias current single channel op amp which has better specifications than LMC6061 ?

It is required for buffering high resistance transducer interfacing application.

Supply voltage range should be plus minus 8V or higher.

The only high-voltage opamp with a lower input bias current is the LMC6001.

Hi BP,

The LMC6001 that Clemens mentioned is a great option for low input bias current with your power supply requirements. What is your target input bias current spec? What is the impedance of your transducer? We also have a new femto-amp input bias current device OPA928 that will be launching very soon that will have the lowest input bias current of all TI devices.

Regards,

Zach

Hi BP,

The advanced product launch is this month where early devices will be available on ti.com. The full release to market is scheduled later this year.
