SBAS512A –APRIL 2011–REVISED APRIL 2011  
20MHz, Second-Order, Isolated Delta-Sigma Modulator  
for Current-Shunt Measurement  
Check for Samples: AMC1204

FEATURES  
DESCRIPTION  
The AMC1204 is a 1-bit digital output, isolated  
2
•
±250mV Input Voltage Range Optimized for  
delta-sigma (ΔΣ) modulator that can be clocked at up  
to 20MHz. 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 4000VPEAK according to UL1577,  
IEC60747-5-2, and CSA standards or specifications.

CSA, IEC60747-5-2, and UL1577 Approved  
Isolation Voltage: 4000VPEAK  
Working Voltage: 1200VPEAK  
Transient Immunity: 15kV/µs  
The AMC1204 provides a single-chip solution for  
measuring the small signal of a shunt resistor across  
an isolated barrier. These types of resistors are  
typically used to sense currents in motor control  
inverters, green energy generation systems, and  
other industrial applications. The AMC1204  
differential inputs easily connect to the shunt resistor  
or other low-level signal sources. An internal  
reference eliminates the need for external  
components. When used with an appropriate external  
digital filter, an effective number of bits (ENOB) of 14  
is achieved at a data rate of 78kSPS.

•
•
Long Isolation Barrier Lifetime (see  
Application Report SLLA197)  
High Electromagnetic Field Immunity  
(see Application Note SLLA181A)  
Outstanding AC Performance:

–
SNR: 84dB (min)  
THD: –80dB (max)  
•
Excellent DC Precision:  
–
–
INL: ±8LSB (max)  
Gain Error: ±2% (max)  
A 5V analog supply (AVDD) is used by the modulator  
while the isolated digital interface operates from a 3V,  
3.3V, or 5V supply (DVDD). The AMC1204 is  
available in an SO-16 (DW) package and is specified  
from –40°C to +105°C.
