Introduction
The AMC1305-Q1 is a high-precision Δ·Σ (ΔΣ) modulator that isolates the output from the input circuit through a capacitive dual isolation barrier with high magnetic field immunity. Per DIN V VDE V 0884-10, UL1577, and CSA standards, the isolation barrier is certified to provide reinforced isolation up to 7000 V. When used with an isolated power supply, the device prevents noise currents on common-mode high-voltage lines from entering the local system ground and interfering with or damaging low-voltage circuits. The AMC1305-Q1 is optimized for direct connection to shunt resistors or other low-voltage signal sources, while delivering excellent DC and AC performance. Shunt resistors are commonly used to sense current in traction inverters, on-board chargers, or similar automotive applications. By using an appropriate digital filter (i.e., integrated in the TMS320F2837x) to decimate the bitstream, the device achieves 16-bit resolution with 85 dB (13.8 ENOB) dynamic range at a 78 kSPS data rate. On the high side, the modulator is powered by a 5 V (AVDD) nominal supply, while the isolated digital interface is powered by a 3.3 V or 5 V supply (DVDD).
