NJU7021/22/24 LOW VOLTAGE C-MOS OPERATIONAL AMPLIFIER GENERAL DESCRIPTION The NJU702i, 22 and 24 are single, dual and quad C-MOS Opera- tional Amplifiers operated on a single-power-supply, low voltage and low operating current. The minimum operating voltage is 3V and the output stage permits output signals to swing between both of the supply rails. The input bias current is as low as less than 1pA, consequently the very small signal around the ground level can be amplified. Furthermore, the operating current is also as low as 150 A(typ) per circuit, therefore it can be applied especially to battery operated items. = FEATURES @ Single-Power-Supply @ Wide Operating Voltage (Vpp=3~ 16V) @ Wide Output Swing Range (Vom=9.98V typ. at V pp=10V) @ Low Operating Current (150 pAscircuit ) @ Low Bias Current (is=1pA) @ Internal Compensation Capacitor @ External Offset Null Adjustment (Only NJU7021) @ Package Outline DIP/DMP/SSOP 8 (NJU7021) DIP/DMP 8 (NJU7022) DIP/DMP/SSOP 14 (NJU7024) C-MOS Technology PIN CONFIGURATION orrset _| mili NC ouT1(] In-(_] Voo In-1] In+(_] OUT IN+1 Cy OFF SET GND[_] oN GNnDI7y WJU70210 WJU70220 WJU7021M WJU7022M WJU7O21Y New Japan Radio Co.Lhd. = PACKAGE OUTLINE WJU70210 WJU7021M WJU70220 4JU7022M WJU70240 NJU7024M NJU70219 WJU7024 o OUT 1 Wi [jouT4 IN-1 1] In-4 IN41 Vop CI IN+2[__| In~-2C_ | OUT 2(_] WJU70240 wJU7024M NJU7024 4-251 NJU7021/22/24 @ EQUIVALENT CIRCUIT 'Vpp ia oS IN-ww 1 o L_ l | at <~> OUT Co L.
