LOW VOLTAGE C-MOS OPERATIONAL AMPLIFIER
■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE
The NJU7031/32/34 are single, dual and quad single supply,
low offset, output full swing C-MOS Operational Amplifiers.
The wide operating voltage 3V to 16V, High slew rate 3.5V/µs
and output full swing are suitable for fast signal processing
amplifiers. Additionally, low input bias current 1pA, and single
supply operation offer amplification of the very small signal
around the ground level.
The NJU7031 has external offset null function.
■ FEATURES
● High Slew Rate 3.5V/µs
● Wide Operating Voltage +3V to +16V
●Output Voltage with full Swing VOM=9.98V typ. (@VDD=10V)
●Input Common Mode Voltage Range
V
ICM=0V to 9V (@VDD=10V)
● Low Bias Current IIB=1pA typ.
● Input Common Mode Voltage range includes ground.
● External Offset Null Adjustment (Only NJU7031)
● C-MOS Technology
● Package Outline NJU7031 (single) DIP8, DMP8, SSOP8
NJU7032 (dual) DIP8, DMP8
NJU7034 (quad) DIP14, DMP14, SSOP14
