OPA928 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.
