OPA128 - Difet Electrometer-Grade OPERATIONAL AMPLIFIER

The OPA128 is an ultra-low bias current monolithic operational amplifier. Using advanced geometry dielectrically-isolated FET (Difet®) inputs, this monolithic amplifier achieves a performance level exceeding even the best hybrid electrometer amplifiers. Laser-trimmed thin-film resistors give outstan.
