The AMC1203 is a precision, galvanically isolated, delta-sigma (ΔΣ) modulator. The isolation barrier separates parts of the system that operate on different common-mode voltage levels. The isolation barrier is highly resistant to magnetic interference and is certified to provide basic isolation of up to 3800VPEAK according to the DIN EN IEC 60747-17 (VDE 0884-17) and UL1577 standards.
The input of the AMC1203 is optimized for direct connection to shunt resistors or other low-impedance signal sources. The output bitstream of the AMC1203 is synchronized to the internally generated clock. Combined with a digital low-pass filter, such as a sinc3, OSR 256 filter, the device achieves 16 bits of resolution with an 87dB dynamic range and a 39kSPS data rate.
The AMC1203 is offered in a SOP-8 gull-wing package (DUB), a SOP-8 package (PSA), and a SOIC-16 package (DW). The device is characterized over the ambient temperature range of –40°C to +105°C.
