NJU7067 14µA/ch, 16V Operation, Rail-to-Rail Output Dual CMOS Operational Amplifier ■GENERAL DESCRIPTION ■PACKAGE OUTLINE The NJU7067 is a low power, high Voltage operation, dual CMOS Operational Amplifier. It is tolerant to RF noise. The NJU7067 can operate wide voltage range from single-supply voltage of +4V to +16V. In addition, this amplifier features Rail-to-Rail output and low input bias current (1pA typ.).Because of these features, the NJU7067 is idea for low side current sense amplifier. ■FEATURES ●Low Supply Current ●Rail-to-Rail Output ●Wide Operating Voltage ●Input Offset Voltage ●Low Input Bias Current ●Slew Rate ●Gain Bandwidth Product ●Enhanced RF Noise Immunity ●Package Outline ●CMOS Process NJU7067M NJU7067V (DMP8) (SSOP8) 14µA/ch typ.
