Order this document by LF347/D 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 8 Low Input Bias Current: 50 pA Low Input Noise Voltage: 16 nV/ ǸHz 1 PIN CONNECTIONS Wide Gain Bandwidth: 4.0 MHz High Slew Rate: 13V/µs Offset Null 1 Noninvt Input 3 Output A 1 2 Inputs A 3 VEE 4 MAXIMUM RATINGS Symbol Value Unit Supply Voltage VCC VEE +18 –18 V Differential Input Voltage VID ±30 V VIDR ±15 V tSC Continuous PD 1/θJA 900 10 TA 0 to +70 TJ 115 Tstg – 65 to +150 Output Short Circuit Duration (Note 2) Power Dissipation at TA = +25°C Derate above TA =+25°C Operating Ambient Temperature Range Operating Junction Temperature Range Storage Temperature Range 7 VCC 6 Output VEE 4 High Common Mode and Supply Voltage Rejection Ratios: 100 dB Input Voltage Range (Note 1) 8 NC – + Invt Input 2 Low Supply Current: 1.8 mA per Amplifier High Input Impedance: 1012 Ω Rating D SUFFIX PLASTIC PACKAGE CASE 751 (SO–8) LF351 (Top View) 5 Offset Null 8 VCC – + LF353 (Top View) 7 Output B – A B 6 Inputs B 5 + N SUFFIX PLASTIC PACKAGE CASE 646 14 1 PIN CONNECTIONS mW mW/°C °C Out 1 1 2 14 Out 4 – – 13 Inputs 4 Inputs 1 3 °C + 1 4 12 + VCC 4 °C 5 11 VEE + Inputs 2 6 NOTES: 1.
