SBAS512E – APRIL 2011 – REVISED SEPTEMBER 2015 AMC1204 20-MHz, Second-Order, Isolated Delta-Sigma Modulator
for Current-Shunt Measurement
1 Features 3 Description The AMC1204 and AMC1204B are 1-bit digital
output, isolated delta-sigma (О”ОЈ) modulators that can
be clocked at up to 20 MHz. The digital isolation of
the modulator output is provided by a silicon dioxide
(SiO2) barrier that is highly resistant to magnetic
interference. This barrier has been certified to provide
basic galvanic isolation of up to 4000 VPEAK
(AMC1204) and 4250 VPEAK (AMC1204B) according
to UL1577, VDE V 0884-10, and CSA standards or
specifications. 1 В±250-mV Input Voltage Range Optimized for
Shunt Resistors
Certified Digital Isolation:
– CSA, VDE V 0884-10, and UL1577 Approved
– Isolation Voltage: 4250 VPEAK (AMC1204B)
– Working Voltage: 1200 VPEAK …
