The OPA928 is a new generation, 16‑V, femtoampere input bias, e-trim™ operational amplifier. This device offers an ultra-low input bias current of 20 fA (max) at 25ºC and 85ºC. The OPA928 input bias performance is tested at production at both temperatures.
The device features near-zero input bias plus outstanding dc precision and ac performance, including rail-to-rail input/output, low offset voltage (±5 µV, typical), low offset drift (±0.1 µV/°C, typical), and low current noise (0.05 fA/√Hz at 0.1 Hz). 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 specified from –40°C to +125°C.
