ADM213EARSZ-REEL Analog Devices Inc.

The ADM2xxE is a family of robust RS-232 and V.28 interface devices that operate from a single 5 V power supply. These products are suitable for operation in harsh electrical environments and are compliant with the EU directive on electromagnetic compatibility (EMC) (89/336/EEC). The level of emissions and immunity are both in compliance. EM immunity includes ESD protection in excess of ±15 kV on all I/O lines (IEC 1000-4-2), fast transient burst protection (IEC 1000-4-4), and radiated immunity (IEC 1000-4-3). EM emissions include radiated and conducted emissions as required by Information Technology Equipment EN 55022, CISPR 22.

All devices fully conform to the EIA-232-E and CCITT V.28 specifications and operate at data rates up to 230 kbps. Shut down and enable control pins are provided on some of the products (see Table 1).

The shutdown function on the ADM211E disables the charge pump and all transmitters and receivers. On the ADM213E the  charge pump, all transmitters, and three of the five receivers are disabled. The remaining two receivers remain active, thereby allowing monitoring of peripheral devices. This feature allows the device to be shut down until a peripheral device begins communication. The active receivers can alert the processor, which can then take the ADM213E out of the shutdown mode. Operating from a single 5 V supply, four external 0.1 μF capacitors are required.

The ADM207E and ADM208E are available in 24-lead PDIP, SSOP, available in 28-lead SSOP, TSSOP, and SOIC_W packages. All products are backward compatible with earlier ADM2xx products, facilitating easy upgrading of older designs.

In the field of communications, transceiver chips play a vital role as they are responsible for sending and receiving data. The 422/485 transceiver chips are commonly used devices in industrial communications. They are characterized by the ability to control the data output of the circuit through enable terminals and are suitable for long-distance and multi-node communication networks. These chips are often used in scenarios such as industrial automation and building automation, providing reliable serial communications.

Analog Devices (ADI), founded in 1965, is headquartered in Norwood, the United States. ADI's data conversion and signal processing technologies have been recognized in the industry. It is a world-leading supplier. ADI has more than 60,000 customers globally, covering all types of electronic equipment manufacturers. ADI is a high-performance analog integrated circuit (IC) manufacturer that has led the industry for more than 40 years and is used in the fields of analog and digital signal processing. It is a world-leading enterprise in IC design, manufacturing, and marketing. Its products involve almost all types of electronic and electrical equipment.

In the field of wearable electronics, ADI has a series of innovative products and solutions. For example, the high-precision, low-power on-chip meter ADuCM350 that supports multiple portable healthcare fields has made milestone progress in several representative major customers at home and abroad. ADI's breakthrough ultra-low-power 3-axis digital MEMS product ADXL362 consumes only 300 nA in motion detection wake-up mode. Its ultra-low-power feature is an ideal solution for wearable motion monitoring devices.
