Overview
The ADM101EARM-REEL7 is a single-channel RS-232 driver and receiver from Analog Devices Inc., part of the Craft Port series. This component is designed to operate from a single 5 V supply, making it highly efficient and suitable for various portable applications. It features a built-in charge-pump voltage inverter that generates an on-chip −5 V supply, eliminating the need for an external negative power supply. This design allows for RS-232 compatible output levels using small charge pump capacitors as small as 0.1 μF.
