® OPA121 Low Cost Precision Difet ® OPERATIONAL AMPLIFIER FEATURES q LOW NOISE: 6nV/√Hz typ at 10kHz q LOW BIAS CURRENT: 5pA max q LOW OFFSET: 2mV max q LOW DRIFT: 3µV/°C typ q HIGH OPEN-LOOP GAIN: 110dB min q HIGH COMMON-MODE REJECTION: 86dB min APPLICATIONS q OPTOELECTRONICS q DATA ACQUISITION q TEST EQUIPMENT q MEDICAL EQUIPMENT q RADIATION HARD EQUIPMENT DESCRIPTION The OPA121 is a precision monolithic dielectricallyisolated FET (Difet ®) operational amplifier. Outstanding performance characteristics are now available for low-cost 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.
