ADM3490EARZ General Description

The ADM3490EARZ is a low power, half-duplex, RS-485 transceiver that operates on a single 3.3V power supply. It is designed for communication networks utilizing the RS-485 protocol, offering a high data rate of up to 250kbps with a short-circuit protection feature. The device features a 1/8 unit load for up to 256 transceivers on the bus, making it suitable for multi-drop configurations. It also includes a low power shutdown mode to minimize power consumption when not in use. The ADM3490EARZ comes in a small, space-saving 8-lead SOIC package, making it ideal for applications where board space is limited. It has a wide operating temperature range of -40°C to +105°C, ensuring reliable performance in harsh industrial environments.

L**n 02/03/2024

Got it to work and I am very satisfied. Using it as surveillance camera with node-red

B**n 03/18/2022

Fast delivery, tested already the one of the two received devices. Works like a charm. Only negative thing is that the 18650 battery holder is just a little bit too small, although i was able to insert the batteries. Battery "pops out" quite easily, but this can be fixed by making a tight box.I ordered it to use it as a UPS for raspberry pi, works fine!
