Product Help

 Hello all,

A customer ask,

" I am looking for an ultra-low input bias, low noise operational amplifier which will be used as a preamplifier of an electrometer for electric field measurements with +-5V dual voltage supply.

I found the LMC6061 and LMP7721. Does this device support dual supply operations (also negative -5V voltage) and What are alternative devices? "

Could anyone help me with this ?

Thank you in advance.
