Zero-drift technology
Amplifiers with zero-drift technology employ a unique, auto-correction technique to avoid system calibration, and no 1/f noise to achieve very high gain circuit configurations.
e-Trim package-level trim technology
Post-assembly polysilicon fuse blowing trim technique enables longevity and long term stability without compromising miniaturization.
Bipolar - super-beta technology
Reduces the input bias current and current drift which minimizes current noise density. The well-matched transistors help achieve very low offset voltages.
JFET Dielectric Isolation technology
The dielectric isolation helps reduce parasitic capacitance and leakage therefore providing better voltage coefficient when compared to the junction capacitance of a non-dielectrically isolated JFET.
