ADM101EWARMZ-REEL7

Overview

The ADM101EWARMZ-REEL7 is a single-channel RS-232 transceiver from the Analog Devices Craft Port series, designed for portable applications. It operates from a single 5 V supply and utilizes an on-chip charge-pump DC-DC converter to generate a negative supply voltage, eliminating the need for external negative rails. The device supports transmission rates up to 460 kbit/s with ±4.2 V output swing. It features ultralow power consumption of 500 μA in active mode and 1 μA in shutdown mode. Qualified for automotive applications, it is housed in a 10-lead MSOP package.

Feature Summary

• Integrated charge-pump DC-DC converter generates internal negative supply from a single 5 V source
• Ultralow power shutdown mode reduces current consumption to 1 μA while keeping the receiver active
• Automotive qualification ensures reliability for controlled manufacturing environments
• Schmitt trigger inputs provide noise immunity and error-free reception

Applications

• Mobile telephones
• Palmtop computers
• Personal digital assistants (PDAs)
• Portable instrumentation
• GPS receivers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and compliance status. Ensure the component meets the required temperature range and automotive qualification standards before integration into the design.

Selection Notes

Select this component when space constraints and low power consumption are critical in portable or automotive designs. The integrated charge pump simplifies the bill of materials by removing the need for negative voltage supplies. Verify that the 460 kbit/s data rate meets the system requirements.

Part Context

This part belongs to the ADM101E series within the Analog Devices Craft Port family. The 'W' suffix indicates automotive qualification, while 'Z' denotes RoHS compliance. The REEL7 designation specifies the tape and reel packaging format used for automated assembly processes.

Replacement Considerations

Compatible substitutes include ADM101EARMZ and ADM101EARMZ-REEL7. These variants share identical electrical specifications but differ in packaging format or lack the automotive qualification indicated by the W suffix.
