MICROCIRCUIT DATA SHEET Original Creation Date: 06/20/95 Last Update Date: 09/12/02 Last Major Revision Date: 09/05/02 MNLF157-X REV 1A1 MONOLITHIC JFET INPUT OPERATIONAL AMPLIFIERS General Description These are the first monolithic JFET input operational amplifiers to incorporate well matched, high voltage JFETs on the same chip with standard bipolar transistors (BI-FET(TM) Technology). These amplifiers feature low input bias and offset currents/low offset voltage and offset voltage drift, coupled with offset adjust which does not degrade drift or common-mode rejection. The devices are also designed for high slew rate, wide bandwidth, extremely fast settling time, low voltage and current noise and a low 1/f noise corner.

Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. Some performance characteristics may degrade when the device is not operated under the listed test conditions. The maximum power dissipation must be derated at elevated temperatures and is dictated by Tjmax (maximum junction temperature), ThetaJA (package junction to ambient thermal resistance), and TA (ambient temperature). The maximum allowable power dissipation at any temperature is Pdmax = (Tjmax - TA)/ThetaJA or the number given in the Absolute Maximum Ratings, whichever is lower. Maximum Power Dissipation is deined by the package characteristics. Operating the part near the Maximum Power Dissipation may cause the part to operate outside guaranteed limits. Unless otherwise specified the absolute maximum negative input voltage is equal to the negative power supply voltage. Human body model, 100pF discharged through 1.5k Ohms. 3 MICROCIRCUIT DATA SHEET MNLF157-X REV 1A1 Electrical Characteristics DC PARAMETERS (The following conditions apply to all the following parameters, unless otherwise specified.)
