±250-mV input, precision current sensing reinforced isolated modulator with Manchester code | DWV | 8 | -40 to 125

The AMC1306 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

7000VPEAK according to the DIN EN IEC 60747-17

(VDE 0884-17) 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 output bitstream of the AMC1306 is Manchester coded (AMC1306Ex) or uncoded

(AMC1306Mx), depending on the derivate. Combined with a digital filter (such as

those in the TMS320F2807x or TMS320F2837x microcontroller families), the device achieves 16 bits of

resolution with a dynamic range of 85dB 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.
