Overview
The ADM101EARMZ-REEL7 is a single-channel RS-232 driver and receiver from Analog Devices Inc., part of the Craft Port series. This device is designed to operate from a single 5 V supply and is highly efficient, making it suitable for portable applications. It features an on-chip charge-pump voltage inverter that generates a -5 V supply, eliminating the need for a negative power supply and allowing for RS-232 compatible output levels using small charge pump capacitors.
