| NJU7021/22/24 LOW VOLTAGE C-MOS OPERATIONAL AMPLIFIER GENERAL DESCRIPTION The NJU7021,22 and 24 are single, dual and quad C-MOS Operational 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 150A ( typ ) per circuit, therefore it can be applied especially to battery operated items. FEATURES Single-Power-Supply Wide Operating Voltage ( VDD=3~16V ) Wide Output Swing Range ( VOM=9.98V typ. @ VDD=10V ) Low Operating Current ( 150A/circuit ) Low Bias Current ( IIB=1pA typ. ) Internal Compensation Capacitor External Offset Null Adjustment ( Only NJU7021 ) Package Outline DIP/DMP/SSOP8 ( NJU7021 ) DIP/DMP8 ( NJU7022 ) DIP/DMP/SSOP14 ( NJU7024 ) C-MOS Technology PIN CONFIGURATION PACKAGE OUTLINE NJU7021D NJU7022D NJU7021M NJU7022M NJU7024D NJU7024M NJU7021V NJU7024V NJU7021D NJU7021M NJU7021V NJU7022D NJU7022M NJU7024D NJU7024M NJU7024V Ver.2003-03-18 -1- NJU7021/22/24 EQUIVALENT CIRCUIT IN1,IN2 are only for NJU7021 ( NJU7022/24 don't have these terminals ). -2- Ver.2003-03-18 NJU7021/22/24 ABSOLUTE MAXIMUM RATINGS ( Ta=25C ) PARAMETER Supply Voltage Differential Input Voltage Common Mode Input Voltage Power Dissipation Operating Temperature Range Storage Temperature Range SYMBOL VDD VID VIC PD Topr Tstg RATINGS 18 18 ( note1 ) -0.3~18 ( DIP14 ) 700 ( DIP8 ) 500 ( DMP8,14 ) 300 ( SSOP8,14 ) 300 -20~+75 -40~+125 UNIT V V V mW C C ( note1 ) If the supply voltage ( VDD ) is less than 18V, the input voltage must not over the VDD level though 18V is limit specified.
