ADM101EARMZ-REEL

The Analog Devices ADM101EARMZ-REEL is a single-channel RS-232 transceiver, part of the Craft Port series, designed for portable applications requiring a compact and low-power serial interface. It operates from a single 5V supply, eliminating the need for a negative power supply by using an efficient charge-pump voltage inverter to generate an on-chip -5V supply.

Key electrical specifications include a transmission rate of 460 kbps, a supply voltage range of 4.5V to 5.5V, and a typical quiescent current of 500 μA, which can be reduced to 1 μA in shutdown mode. The device offers ±4.2V output swing with a 5V supply and features receiver input overvoltage protection up to ±30V and ESD protection on all I/O pins exceeding 15 kV.

Packaged in a 10-lead MSOP, the ADM101EARMZ-REEL is suitable for space-constrained designs. Its applications include mobile telephones, PDAs, portable instrumentation, and GPS receivers where low power drain and small size are critical. The transceiver provides one driver and one receiver, with full duplex communication.

This device is qualified for automotive applications. Its epitaxial BiCMOS construction minimizes power consumption and guards against latch-up. The shutdown input disables the charge pump, putting the device into a low-power state while the receiver remains functional.
