Product Overview

The OPA2111BM is a high precision monolithic dielectrically isolated FET (Difet) Operational Amplifier for use with detector arrays. 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 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 patented circuit design techniques. A cascade design allows high precision input specifications and reduced susceptibility to flicker noise. Standard dual op amp pin configuration allows upgrading of existing designs to higher performance levels.
  • 100% tested, 8nV/√Hz at 10kHz Maximum low noise
  • 4pA Maximum low bias current
  • 500µV Maximum low offset
  • 2.8µV/°C Low drift
  • 114dB Minimum high open-loop gain
  • 96dB Minimum high common-mode rejection
  • Green product and no Sb/Br
