The AD8418 is a high voltage, high resolution current shunt amplifier. It features an initial gain of 20 V/V, with a maximum ±0.15% gain error over the entire temperature range. The buffered output voltage directly interfaces with any typical converter. The AD8418 offers excellent input common-mode rejection from −2 V to +70 V. The AD8418 performs bidirectional current measurements across a shunt resistor in a variety of automotive and industrial applications, including motor control, battery management, and solenoid control.

he AD8418 offers breakthrough performance throughout the −40°C to +125°C temperature range. It features a zero drift core, which leads to a typical offset drift of 0.1 µV/°C throughout the operating temperature range and the common-mode voltage range. The AD8418 is fully qualified for automotive applications and includes EMI filters and patented circuitry to enable output accuracy with pulse-width modulation (PWM) type input common-mode voltages. The typical input offset voltage is ±200 µV. The AD8418 is offered in 8-lead MSOP and SOIC packages.

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.

• Internally frequency compensated for unity gain
• 45nA Low input biasing current
• 2mV Low input offset voltage
• 5nA Offsets current
• Input common-mode voltage range includes ground
• Differential input voltage range equal to the power supply voltage

The OPA340NA/3K is a single-supply Operational Amplifier optimized for low-voltage. High-speed operation make them ideal for driving sampling analogue-to-digital (A/D) converters. They are also well-suited for general purpose and audio applications as well as providing I/V conversion at the output of digital-to-analogue (D/A) converters. Single version have identical specifications for design flexibility. The OPA340 series operate on a single supply as low as 2.5V with an input common-mode voltage range that extends 500mV below ground and 500mV above the positive supply. Output voltage swing is to within 1mV of the supply rails with a 100k load.
