NJU7068
14µA/ch, 16V Operation, Rail-to-Rail Output
Quad CMOS Operational Amplifier
■GENERAL DESCRIPTION
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.
