The AMC1035-Q1 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 voltage and temperature sensing applications.
Select the output bitstream of the AMC1035-Q1 to be Manchester coded to prevent setup and hold time requirement considerations of the receiving device and to 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-Q1 supports a ratiometric circuit architecture to minimize the negative impact of the supply voltage variation and temperature drift on the accuracy of the measurement.
The AMC1035-Q1 can also be used for high common-mode AC voltage sensing with a digital isolator and isolated power supply.
