8.2 Typical Application

The AMC1306M05-Q1 is ideally suited for shunt-based, current-sensing applications where accurate current monitoring is required in the presence of high common-mode voltages.

Figure 8-1 shows the AMC1306M05-Q1 in a typical application. The load current flowing through an external shunt resistor RSHUNT produces a voltage drop that is sensed by the AMC1306M05-Q1. The AMC1306M05-Q1 digitizes the analog input signal on the high-side, transfers the data across the isolation barrier to the low-side, and outputs the digital bitstream on the DOUT pin. The 5-V high-side power supply (AVDD) is generated from the floating gate driver supply using a resistor (R4) and a Zener diode (D1).

The differential input, digital output, and the high common-mode transient immunity (CMTI) of the AMC1306M05-Q1 ensure reliable and accurate operation even in high-noise environments.
