Description
General part information
OPA928 Series
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.
