MNLF157-X REV 1A1 MICROCIRCUIT DATA SHEET
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.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.
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.
Note 2: 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.
Note 3: 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.
Note 4: Unless otherwise specified the absolute maximum negative input voltage is equal to
the negative power supply voltage.
Note 5: Human body model, 100pF discharged through 1.5k Ohms.
