ON Semiconductor LF347, B LF351 LF353 JFET Input Operational Amplifiers These low cost JFET input operational amplifiers combine two state-of-the-art analog technologies on a single monolithic integrated circuit. Each internally compensated operational amplifier has well matched high voltage JFET input devices for low input offset voltage. The JFET technology provides wide bandwidths and fast slew rates with low input bias currents, input offset currents, and supply currents. These devices are available in single, dual and quad operational amplifiers which are pin-compatible with the industry standard MC1741, MC1458, and the MC3403/LM324 bipolar devices. * Input Offset Voltage of 5.0 mV Max (LF347B) * * * * * * * FAMILY OF JFET OPERATIONAL AMPLIFIERS N SUFFIX PLASTIC PACKAGE CASE 626 8 1 D SUFFIX PLASTIC PACKAGE CASE 751 (SO-8) Low Input Bias Current: 50 pA Low Input Noise Voltage: 16 nV/ Hz 8 1 Wide Gain Bandwidth: 4.0 MHz PIN CONNECTIONS High Slew Rate: 13V/s Low Supply Current: 1.8 mA per Amplifier High Input Impedance: Offset Null 1 High Common Mode and Supply Voltage Rejection Ratios: 100 dB Noninvt Input 3 Inputs A MAXIMUM RATINGS Value Unit Supply Voltage VCC VEE +18 -18 V Differential Input Voltage VID 30 V Input Voltage Range (Note 1) VIDR 15 V tSC Continuous PD 1/JA 900 10 Output Short Circuit Duration (Note 2) Power Dissipation at TA = +25C Derate above TA =+25C 2 3 VEE 4 Symbol 7 VCC LF351 (Top View) 6 Output VEE 4 Output A 1 Rating 8 NC + Invt Input 2 1012 5 Offset Null + - A B + 8 VCC 7 Output B 6 LF353 (Top View) Inputs B 5 N SUFFIX PLASTIC PACKAGE CASE 646 14 1 PIN CONNECTIONS mW mW/C Operating Ambient Temperature Range TA 0 to +70 C Operating Junction Temperature Range TJ 115 C Storage Temperature Range Tstg - 65 to +150 C NOTES: 1. Unless otherwise specified, the absolute maximum negative input voltage is limited to the negative power supply. 2. Any amplifier output can be shorted to ground indefinitely. However, if more than one amplifier output is shorted simultaneously, maximum junction temperature rating may be exceeded.
