The ADE12021 is a dual channel, configurable, isolated digital input monitoring solution for energy transmission and distribution applications. The ADE1202 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 ADE1202 digital output signal on the DOUTx pins 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 ADE1202 application circuit accepts a wide range of input voltages from 10 V dc to 300 V, 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 ADE1202 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.
Note that throughout this data sheet, multifunction pins, such as DOUT2/IRQ, are referred to either by the entire pin name or by a single function of the pin, for example, DOUT2, when only that function is relevant.

Evaluation Kits (1)
The EVAL-ADE1202EBZ is a full featured evaluation board, designed to allow the user to easily evaluate the ADE1202 dual-channel, configurable, isolated digital binary input IC performance in a context similar to a real binary input interface application. The evaluation kit requires purchasing the controller board for the system demonstration platform (EVAL-SDP-CB1Z). The evaluation kit includes evaluation software, written in LabVIEW®, which provides access to the registers and features of the device through a PC interface.
Consult the ADE1202 data sheet in conjunction with this user guide when using the EVAL-ADE1202EBZ.
