OPA2111 - Burr-Brown

OPA2111 Dual Low Noise Precision Difet OPERATIONAL AMPLIFIER

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 lo.
