Precision op amp technologies

checkmark

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.

checkmark

e-Trim package-level trim technology

Post-assembly polysilicon fuse  blowing trim technique enables longevity and long term stability without compromising miniaturization.

checkmark

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.

checkmark

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.
