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.

Texas Instruments LM7321MF/NOPB
The LM7321MF/NOPB is a single high output current Operational Amplifier with rail-to-rail input and output. The LM732xx family is efficient, achieving 18V/µs slew rate and 20MHz unity gain bandwidth while requiring only 1mA of supply current per op amp. The LM732xx device performance is fully specified for operation at 2.7V, ±5 and ±15V. The LM732xx device is designed to drive unlimited capacitive loads without oscillations. Greater than rail-to-rail input common-mode voltage range with 50dB of common-mode rejection across this wide voltage range, allows both high-side and low-side sensing. Most device parameters are insensitive to power supply voltage and this makes the parts easier to use where supply voltage may vary, such as automotive electrical systems and battery powered equipment. This amplifier has true rail-to-rail output and can supply a respectable amount of current (15mA) with minimal head-room from either rail (300mV) at low distortion (0.05% THD+noise).

Analog Devices / Linear Technology LTC1540IMS8#PBF
The LTC1540IMS8#PBF is an ultralow nano-power single Comparator with built-in reference. The comparator features include less than 0.6µA supply current over the commercial temperature range, a 1.182V±2% reference, programmable hysteresis and TTL/CMOS outputs that sink and source current. The reference output can drive a bypass capacitor of up to 0.01µF without oscillation. The comparator operates from a single 2 to 11V supply or a dual ±1 to ±5.5V supply. Comparator hysteresis is easily programmed by using two resistors and the HYST pin. The comparator input operates from the negative supply to within 1.3V of the positive supply. The comparator output stage can continuously source up to 40mA. By eliminating the cross-conducting current that normally occur when the comparator changes logic states, power supply glitches are eliminated.
