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 V VDE V 0884-10, 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 while supporting excellent DC and AC performance. Applications include shunt resistor-based current sensing and isolated voltage sensing. With an appropriate digital filter, 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.
