The AMC1305 is a precision, delta-sigma (ΔΣ) modulator with the output separated from the input circuitry by a capacitive double isolation barrier that is highly resistant to magnetic interference. This barrier is certified to provide reinforced isolation of up to 7000 VPEAK according to the DIN VDE V 0884-11, UL1577, and CSA standards. Used in conjunction with isolated power supplies, the device prevents noise currents on a high common-mode voltage line from entering the local system ground and interfering with or damaging low voltage circuitry.
The AMC1305 is optimized for direct connection to shunt resistors or other low voltage level signal sources and supports excellent dc and ac performance. Shunt resistors are typically used to sense currents in motor drives, green energy generation systems, or other industrial applications. By using an appropriate digital filter (that is, as integrated on the TMS320F2837x) to decimate the bit stream, the device can achieve 16 bits of resolution with a dynamic range of 85 dB (13.8 ENOB) at a data rate of 78 kSPS.
On the high-side, the modulator is supplied with a nominal voltage of 5 V (AVDD), whereas the isolated digital interface operates from a 3.3-V or 5-V power supply (DVDD).
The AMC1305 is available in a wide-body SOIC-16 (DW) package and is specified from –40°C to +125°C.
