OPA2111 kp dual low noise difet opamp, pro audio dip-8
LOW NOISE: 100% Tested, 8nV/ Hz max at 10kHz
HIGH OPEN-LOOP GAIN: 114dB min
HIGH COMMON-MODE REJECTION: 96dB min
The OPA2111 is a high precision monolithic dielectrically isolated FET (
Difet ) operational amplifier. 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 amplifiers.
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 cascode design allows high precision input specifications and reduced susceptibility to flicker noise.
