3 Description
The AMC1306 device 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
8000 VPEAK according to the DIN V VDE V 0884-10
and UL1577 standards. Used in conjunction with
isolated power supplies, this isolated modulator
separates parts of the system that operate on
different common-mode voltage levels and protects
lower-voltage parts from damage.
The input of the AMC1306 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
and supports excellent ac and dc performance. The
output bitstream of the AMC1306 is Manchester
coded (AMC1306Ex) or uncoded (AMC1306Mx),
depending on the derivate. By using an integrated
digital filter (such as those in the TMS320F2807x or
TMS320F2837x microcontroller families) to decimate
the bitstream, the device can achieve 16 bits of
resolution with a dynamic range of 85 dB at a data
rate of 78 kSPS.
The bitstream output of the Manchester coded
AMC1306Ex versions support single-wire data and
clock transfer without having to consider the setup
and hold time requirements of the receiving device.

(1) Apply creepage and clearance requirements according to the specific equipment isolation standards of an application. Care must be
taken to maintain the creepage and clearance distance of a board design to ensure that the mounting pads of the isolator on the printed
circuit board (PCB) do not reduce this distance. Creepage and clearance on a PCB become equal in certain cases. Techniques such as
inserting grooves and ribs on the PCB are used to help increase these specifications.
(2) This coupler is suitable for safe electrical insulation only within the safety ratings. Compliance with the safety ratings shall be ensured by
means of suitable protective circuits.
(3) Testing is carried out in air or oil to determine the intrinsic surge immunity of the isolation barrier.
(4) Apparent charge is electrical discharge caused by a partial discharge (pd).
(5) All pins on each side of the barrier are tied together, creating a two-pin device.
