OPA128 - Difet Electrometer-Grade OPERATIONAL AMPLIFIER

Download the OPA128 datasheet PDF. This datasheet also covers the OPA128_Burr variant, as both devices belong to the same difet electrometer-grade operational amplifier family and are provided as variant models within a single manufacturer datasheet.

Description

The OPA128 is an ultra-low bias current monolithic operational amplifier.

Using advanced geometry dielectrically-isolated FET (Difet®) inputs, this monolithic amplifier achieves a performance level exceeding even the best hybrid electrometer amplifiers.

Features

  • q ULTRA-LOW BIAS.
