The OPA606 is a wide-bandwidth monolithic dielectrically-isolated FET (Difet ®) operational ampli- fier featuring a wider bandwidth and lower bias cur- rent than BIFET® LF156A amplifiers. Bias current is specified under warmed-up and operating conditions, as opposed to a junction temperature of +25°C. Laser-trimmed thin-film resistors offer improved off- set voltage and noise performance. The OPA606 is internally compensated for unity-gain stability.
