The AMC1035 is a precision delta-sigma (ΔΣ) modulator that operates from a single 3.0-V to 5.5-V supply and with an externally supplied clock signal in the range of 9 MHz to 21 MHz. In Manchester mode, the specified clock range is 9 MHz to 11 MHz. The differential ±1-V input structure of the device is optimized for high noise environments typical for industrial applications.
Select the output bitstream of the AMC1035 to be Manchester coded to prevent setup and hold time requirement considerations of the receiving device and reduce overall circuit layout efforts. When used with a digital filter (such as integrated in the TMS320F28004x, TMS320F2807x or TMS320F2837x microcontroller families) to decimate the output bitstream, the device can achieve 16 bits of resolution with a dynamic range of 87 dB at a data rate of 82 kSPS.
The internal reference source of the AMC1035 supports ratiometric circuit architecture to minimize the negative impact of the supply voltage variation and temperature drift on the accuracy of the measurement.
The AMC1035 can also be used for AC power line voltage sensing with a digital isolator and isolated power supply.
