The AMC1311 device is a precision, isolated amplifier with an isolation barrier that is highly resistant to magnetic interference between the output and the input circuitry. According to VDE V 0884-11 and UL1577, this barrier is certified to provide reinforced galvanic isolation of up to 7 kVPEAK. This isolated amplifier separates portions of the system that run on different common-mode voltage levels and protects lower-voltage parts from damage when used in conjunction with isolated power supply.

The MSP430 is an ultra-low-power microcontroller including numerous devices with diverse peripheral sets aimed at different applications. The architecture is optimized for extended battery life in portable measurement applications, thanks to five low-power modes.
The device is equipped with a powerful 16-bit RISC CPU, 16-bit registers, and constant generators, all of which help to code efficiency. The digitally controlled oscillator (DCO) enables a one-second transition from low-power to active mode.

The LD111733CTR is a linear regulator having a fixed output voltage of 3.3V, a maximum current of 1.34A, and a SOT-223 SMD packaging. The linear regulator's power dissipation is reduced by the low dropout voltage of 1V (typical @100mA). This is helpful in situations where a linear regulator's improved line regulation and energy economy are required. The supply voltage rejection is 75db, and the output voltage is 100V with minimal noise. For stability, the LD1117S33CTR just requires a single 10uF capacitor.
