ADM101E is a tiny RS-232 transceiver designed for portable applications. It features a transmission rate of 460 kbit/s and is compatible with RS-232 input/output levels. The transceiver operates from a single 5V power supply and includes one driver and one receiver. It also incorporates an on-board DC-DC converter, eliminating the need for a negative power supply. The ADM101E is low power and has an ultralow power shutdown mode. It is suitable for mobile telephones, palmtop computers, PDAs, portable instrumentation, and GPS receivers.
The ADM101E is a compact RS‑232 compatible line driver and receiver designed for portable applications such as mobile phones, palmtop computers and PDAs. It operates from a single 5 V supply and uses an on‑chip charge‑pump to generate the required –5 V rail, eliminating the need for an external negative supply.
Key features include a 460 kbit/s transmission rate, +4.2 V output swing, ultra‑low shutdown current (<1 µA), and protection against over‑voltage and ESD. The device is supplied in a 10‑lead uSOIC (RM‑10) package and provides separate driver and receiver pins with standard RS‑232 voltage levels.
