3 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.

The near-zero input bias is complemented by

outstanding dc precision and ac performance,

including rail-to-rail input and output, low offset

voltage (±5μV, typical), low offset drift (±0.1μV/°C,

typical), and ultra-low current noise (0.07fA/√Hz

at 0.1Hz). These features make the OPA928 an

excellent choice for low-light photodiode and high

source-impedance applications.

The OPA928 features an internal, high precision

guard buffer to protect high impedance input

traces from undesirable current leakage in sensitive

applications. The OPA928 packaging and pin out is

designed to support low-leakage circuit designs.

The OPA928 is the next generation OPA128.
