- Fully specified over extended industrial temperature range: –40°C to +125°C
The AMC1333M10 is a precision, delta-sigma (ΔΣ) modulator with the output separated from the input circuitry by an isolation barrier that is highly resistant to magnetic interference. This barrier is certified to provide reinforced isolation of up to 8000 VPEAK according to the DIN EN IEC 60747-17 (VDE 0884-17) and UL1577 standards, and supports a working voltage up to 1.5 kVRMS. The isolation barrier separates parts of the system that operate on different common-mode voltage levels and protects the low-voltage side from voltages that can cause electrical damage or be harmful to an operator.
The wide, bipolar, ±1-V input voltage range of the AMC1333M10 and its high input resistance support direct connection of the device to resistive dividers in high-voltage applications. The output bitstream of the AMC1333M10 is synchronized to the internally generated clock. By using an integrated digital filter (such as those in the TMS320F2807x or TMS320F2837x microcontroller families) to decimate the bitstream, the device can achieve 16 bits of resolution with a dynamic range of 87 dB at a data rate of 39 kSPS.
The AMC1333M10 is offered in a 8-pin, wide-body, SOIC package and is fully specified over the extended industrial temperature range of –40°C to +125°C.
