Noise-Free Cascode* OPA2111 Simplified Circuit (Each Amplifier) 8 4 Output +V CC –V CC –In +In *Patented OPA2111 ® DESCRIPTION The OPA2111 is a high precision monolithic dielectrically isolated FET (Difet ) operational ampli- fier. Outstanding performance characteristics allow its use in the most critical instrumentation applications. Noise, bias current, voltage offset, drift, open-loop gain, common-mode rejection, and power supply re- jection are superior to BIFET® amplifiers. Very low bias current is obtained by dielectric isola- tion with on-chip guarding. Laser trimming of thin-film resistors gives very low offset and drift. Extremely low noise is achieved with patented circuit design techniques. A cascode design allows high precision input specifications and reduced susceptibility to flicker noise. Standard dual op amp pin configuration allows up- grading of existing designs to higher performance levels. © 1984 Burr-Brown Corporation PDS-540E Printed in U.S.A. October, 1993 |
