High-Precision, Reinforced Isolated Delta-Sigma Modulators
1 Features 3 Description The AMC1305 device is a precision, delta-sigma (О”ОЈ)
modulator with the output separated from the input
circuitry by a capacitive double isolation barrier that is
highly resistant to magnetic interference. This barrier
is certified to provide reinforced isolation of up to
7000 VPEAK according to the DIN V VDE V 0884-10,
UL1577, and CSA standards. Used in conjunction
with isolated power supplies, the device prevents
noise currents on a high common-mode voltage line
from entering the local system ground and interfering
with or damaging low voltage circuitry. 1 Pin-Compatible Family Optimized for ShuntResistor-Based Current Measurements:
– ±50-mV or ±250-mV Input Voltage Ranges
– CMOS or LVDS Digital Interface Options
Excellent DC Performance Supporting HighPrecision Sensing on System Level:
– Offset Error: В±50 ВµV or В±150 ВµV (max) …
