GENERAL DESCRIPTION

digital input monitoring solution for energy transmission and

distribution applications. The ADE1201 is configured through

the serial port interface (SPI) to perform an isolated measurement

of the digital input that is also called binary input or contact

input. The ADE1201 digital output signal on the DOUT1 pin

reflects the state of the input signal after user configurable

signal conditioning. The SPI protocol supports addressing to

allow up to eight devices sharing one 4-wire SPI port.

The ADE1201 application circuit accepts a wide range of input

voltages from ±10 V dc to ±300 V dc, or 8 V rms to 240 V rms.

The programmable wetting current and robust application

circuit enable the device to meet stringent, system level

electromagnetic capability (EMC) requirements.

The ADE1201 includes an isoPower® integrated, isolated dc-to-dc

converter that eliminates the need for an external isolated power

supply. The iCoupler® chip scale transformer technology is

used to isolate the logic signals between the high voltage,

isolated side and the low voltage, nonisolated side of the

digital input monitor. This technology creates a small form

factor design that includes data and power isolation.

An integrated successive approximation register (SAR)

analog-to-digital converter (ADC) and a programmable gain

amplifier (PGA) from 1× to 10× measure the analog inputs.

The ADC waveforms are available through the SPI port to

allow system level diagnostics.
