| Order this document by TL081C/D TL081C,AC JFET Input Operational Amplifiers These low-cost JFET input operational amplifiers combine two state-of- the-art linear 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 BIFET 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 products. * Input Offset Voltage Options of 6.0 mV and 15 mV Max TL082C,AC TL084C,AC JFET INPUT OPERATIONAL AMPLIFIERS SEMICONDUCTOR TECHNICAL DATA * * * * * * Low Input Bias Current: 30 pA Low Input Offset Current: 5.0 pA Wide Gain Bandwidth: 4.0 MHz High Slew Rate: 13 V/s Low Supply Current: 1.4 mA per Amplifier High Input Impedance: 1012 8 8 1 1 P SUFFIX PLASTIC PACKAGE CASE 626 D SUFFIX PLASTIC PACKAGE CASE 751 (SO-8) PIN CONNECTIONS ORDERING INFORMATION Op Amp Function Single Device TL081CD TL081ACP TL082CD Dual Quad TL082ACP TL084CN, ACN Operating Temperature Range TA = 0 to +70C TA = 0 to +70C TA = 0 to +70C Offset Null 1 Package SO-8 Plastic DIP SO-8 Plastic DIP Plastic DIP Inv + Input 2 Noninvt Input 3 VEE 4 + 8 NC 7 VCC 6 Output 5 Offset Null TL081 (Top View) Output A 1 Inputs A 2 3 - + - + 8 VCC VEE 4 7 Output B 6 Inputs B 5 TL082 (Top View) Representative Circuit Schematic (Each Amplifier) Output Q4 Q3 Q6 - Inputs + J1 J2 Q17 Q20 Q15 Q14 Q21 Q12 Q10 Q13 Q11 Q16 Q9 Q8 Q7 Q25 Q22 Q24 10 pF Q19 Q23 24 J3 2.0 k Q5 Q2 Q1 14 1 VCC N SUFFIX PLASTIC PACKAGE CASE 646 PIN CONNECTIONS Output 1 1 Inputs 1 2 3 VCC 4 Inputs 2 5 6 Output 2 7 + - - + - + 14 Output 4 13 12 11 VEE 2 3 + - Inputs 4 1 4 10 9 Inputs 3 Offset Null (TL081 only) Q18 1.5 k 1.5 k Bias Circuitry Common to All Amplifiers VEE 8 Output 3 TL084 (Top View) (c) Motorola, Inc. 1997 Rev 1 MOTOROLA ANALOG IC DEVICE DATA 1 TL081C,AC TL082C,AC TL084C,AC MAXIMUM RATINGS Rating Supply Voltage Differential Input Voltage Input Voltage Range (Note 1) Output Short Circuit Duration (Note 2) Power Dissipation Plastic Package (N, P) Derate above TA = +47C Operating Ambient Temperature Range Storage Temperature Range PD 1/JA TA Tstg 680 10 0 to +70 -65 to +150 mW mW/C C C Symbol VCC VEE VID VIDR tSC Value 18 -18 30 15 Continuous Unit V V V NOTES: 1.
