ZHCSH46C December 2017 – June 2022 AMC1311
PRODUCTION DATA
Figure 9-1 shows the AMC1311 in a typical application. The DC bus voltage
is divided down to an approximate
2-V level across the
bottom resistor (RSNS) of a high-impedance resistive divider that is sensed by the
AMC1311. The AMC1311 digitizes the analog
input signal on the high-side, transfers the data across the isolation barrier to
the low-side, reconstructs the analog signal, and presents this signal as a
differential voltage signal on the output pins.
The high-impedance input and the high common-mode transient immunity (CMTI) of the AMC1311 ensure reliable and accurate operation even in high-noise environments.
