OPA129 OPA129 OPA129 SBOS026A – JANUARY 1994 – REVISED APRIL 2007 Ultra-Low Bias Current Difet® OPERATIONAL AMPLIFIER FEATURES q ULTRA-LOW BIAS CURRENT: 100fA max q LOW OFFSET: 2mV max q LOW DRIFT: 10µV/°C max q HIGH OPEN-LOOP GAIN: 94dB min q LOW NOISE: 15nV/√Hz at 10kHz q PLASTIC DIP AND SO PACKAGES DESCRIPTION The OPA129 is an ultra-low bias current monolithic operational amplifier offered in an 8-pin PDIP and SO-8 package. Using advanced geometry dielectrically-isolated FET (Difet®) inputs, this monolithic amplifier achieves a high performance level. Difet fabrication eliminates isolation-junction leakage current—the main contributor to input bias current with conventional monolithic FETs. This reduces input bias current by a factor of 10 to 100.
