7.1 Overview

The differential analog input (comprised of input signals AINP and AINN) of the AMC1035 is a chopper-stabilized buffer, followed by the switched-capacitor input of a second-order, delta-sigma (ΔΣ) modulator stage that digitizes the input signal into a 1-bit output stream. The data output DOUT of the converter provides a stream of digital ones and zeros that is synchronous to the externally-provided clock source at the CLKIN pin with a frequency in the range of 9 MHz to 21 MHz. The time average of this serial bitstream output is proportional to the analog input voltage.

The Functional Block Diagram section shows a detailed block diagram of the AMC1035. The 1.6-GΩ differential input resistance of the analog input stage supports low gain-error signal sensing in high-voltage applications using resistive dividers. The external clock input simplifies the synchronization of multiple measurement channels on the system level. The extended frequency range of up to 21 MHz supports higher performance levels compared to the other solutions available on the market.
