ADE1201ACCZ-RL

ADCs/DACs - Special Purpose Overview

The ADE1201ACCZ-RL is a single-channel, configurable isolated digital input monitor designed for energy transmission and distribution applications. It accepts wide voltage ranges from ±10 V dc to ±300 V dc or 8 V rms to 240 V rms ac. The device integrates an isoPower isolated dc-to-dc converter, eliminating the need for external isolated power supplies. It features a programmable load with pulsed current up to 205 mA and constant current up to 6.3 mA. An internal SAR ADC with PGA provides system diagnostics via SPI. Operating on a single 3.3 V supply, it supports temperatures from −40°C to +125°C in a 20-lead LGA package.

ADCs/DACs - Special Purpose Procurement Notes

Verify component authenticity through authorized Analog Devices distributors. Confirm the specific ACCZ-RL suffix matches the required reel packaging and RoHS compliance status. Check for pending regulatory approvals such as CSA and VDE certificates before final integration into safety-critical designs.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring robust isolation of high-voltage binary inputs. Ensure the system operates within the specified 3.3 V supply range. Consider the thermal resistance characteristics when designing PCB layouts for high ambient temperatures up to 125°C. Verify that the 20-lead LGA package fits the available footprint constraints.

ADCs/DACs - Special Purpose Part Context

The ADE1201 belongs to Analog Devices' family of isolated digital input monitors utilizing iCoupler technology. It is distinct from general-purpose isolators by integrating analog signal conditioning and power generation. The ACCZ-RL designation indicates the specific tape-and-reel packaging variant of the standard ADE1201 device.

ADCs/DACs - Special Purpose Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other Analog Devices isolated input solutions based on channel count and isolation voltage requirements if replacement is necessary.
