NJU7068 14µA/ch, 16V Operation, Rail-to-Rail Output Quad CMOS Operational Amplifier ■GENERAL DESCRIPTION ■PACKAGE OUTLINE The NJU7068 is a low power, high Voltage operation, quad CMOS Operational Amplifier. It is tolerant to RF noise. The NJU7068 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 NJU7068 is ideal 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 ■PIN CONFIGURATION (Top View) 1 14 2 13 3 ■APPLICATION CIRCUIT R2 VOUT R3 R4 (SSOP14) DMP14,SSOP14 4 R1 NJU7068V (DMP14) 14µA/ch typ.
