3 Description
The AMC1304-Q1 is a precision, delta-sigma (ΔΣ)
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.
The input of the AMC1304-Q1 is optimized for direct
connection to shunt resistors or other low voltage-
level signal sources. The unique low input voltage
range of the ±50-mV device allows significant
reduction of the power dissipation through the shunt
while supporting excellent ac and dc performance. By
using an appropriate digital filter (that is, as integrated
on the TMS320F2807x or TMS320F2837x families) to
decimate the bit stream, the device can achieve 16
bits of resolution with a dynamic range of 81 dB (13.2
ENOB) at a data rate of 78 kSPS.
On the high-side, the modulator is supplied by an
integrated low-dropout (LDO) regulator that allows an
unregulated input voltage between 4 V and 18 V
(LDOIN). The isolated digital interface operates from
a 3.3-V or 5-V power supply (DVDD).
The AMC1304-Q1 is available in a wide-body SOIC-
16 (DW) package.
