Product Description

The OPA121KU is a precision monolithic dielectrically-isolated FET (Difet®) Operational Amplifier for use with radiation hard equipment. Noise, bias current, voltage offset, drift, open-loop gain, common-mode rejection and power supply rejection are superior to BIFET® amplifier. Very low bias current is obtained by dielectric isolation with on-chip guarding. Laser-trimming of thin-film resistors gives very low offset and drift. Extremely low noise is achieved with new circuit design techniques (patented). A new cascade design allows high precision input specifications and reduced susceptibility to flicker noise. Standard 741 pin configuration allows upgrading of existing designs to higher performance levels.
