OPA928 Datasheet Operational Amplifier

Manufacturer: Texas Instruments

Overview: OPA928 SBOSA77A – MARCH 2023 – REVISED APRIL 2024 OPA928 36V, Femtoampere Input Bias, Precision, Rail-to-Rail Input/Output, e‑trim™ Operational Amplifier.

General Description

The OPA928 is a new generation, 36V, femtoampere input bias, e-trim™ operational amplifier.

This device offers an ultra-low input bias current of 20fA (max) across the entire industrial temperature range, −40ºC to +85ºC.

The OPA928 input bias performance is tested at production at both temperatures.
