| NJU7031/32/34 LOW VOLTAGE C-MOS OPERATIONAL AMPLIFIER GENERAL DESCRIPTION The NJU7031,32 and 34 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 1mA ( 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 ( 1mA/circuit ) Low Bias Current ( IIB=1pA typ. ) Internal Compensation Capacitor External Offset Null Adjustment ( Only NJU7031 ) Package Outline DIP/DMP/SSOP8 ( NJU7031 ) DIP/DMP8 ( NJU7032 ) DIP/DMP/SSOP14 ( NJU7034 ) C-MOS Technology PIN CONFIGURATION PACKAGE OUTLINE NJU7031D NJU7032D NJU7031M NJU7032M NJU7034D NJU7034M NJU7031V NJU7034V NJU7031D NJU7031M NJU7031V NJU7032D NJU7032M NJU7034D NJU7034M NJU7034V Ver.2003-03-18 -1- NJU7031/32/34 EQUIVALENT CIRCUIT The terminals IN1, IN2 are only for NJU7031 ( NJU7032/34 don't have these terminals ). -2- Ver.2003-03-18 NJU7031/32/34 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.
