The LM124J is a low power quad Operational Amplifier designed to operate from a single power supply over a wide range of voltages. Operation from split-power supplies is also possible and the low-power supply current drain is independent of the magnitude of the power supply voltage. Application areas include transducer amplifiers, DC gain blocks and all the conventional op-amp circuits which now can be more easily implemented in single power supply systems. For example, the LM124 series can directly operate off of the standard 5V power supply voltage which is used in digital systems and easily provides the required interface electronics without requiring the additional ±15V power supplies.

The ACPL-C79B-000E is a precision miniature Isolation Amplifier designed for current and voltage sensing in electronic power converters. It operates from a single 5V supply and provides excellent linearity and dynamic performance of 60dB SNR. The amplifier with 200kHz bandwidth, 1.6µs fast response time, the product captures transients in short-circuit and overload conditions. The high common-mode transient immunity provides the precision and stability needed to accurately monitor motor current in high noise motor control environments, providing for smoother control in various types of motor control applications. In a typical motor drive implementation, current flows through an external resistor and the resulting analogue voltage drop is sensed by the isolation amplifier.
