ADM230LAN

Overview

The ADM230LAN is a low-power, 5 V-powered CMOS RS-232 transceiver manufactured by Analog Devices Inc. It integrates charge pump circuitry to generate the necessary voltages for RS-232 signal levels from a single 5 V supply, eliminating the need for external dual-voltage sources. The device features two drivers and two receivers, providing full RS-232 communication capabilities in a compact package. It operates within a temperature range of -40°C to +85°C and is designed for applications requiring reliable serial communication with minimal power consumption and component count.

Feature Summary

• Integrated charge pump eliminates requirement for external dual-voltage supplies
• Low power consumption design suitable for battery-operated systems
• CMOS technology ensures compatibility with standard logic families

Applications

• Portable computers and notebook PCs
• Battery-powered data acquisition systems
• Industrial control panels requiring RS-232 connectivity

Procurement Notes

Verify the specific suffix 'LA' indicates the lead-free and RoHS-compliant variant when sourcing. Confirm the package type matches the required PCB footprint, typically SOIC or DIP, as manufacturing batches may vary. Ensure the supplier provides official documentation confirming the analog devices origin and compliance status prior to purchase.

Selection Notes

Select this component when a single 5 V supply is available and low power dissipation is critical. It serves as a direct replacement for older bipolar RS-232 transceivers that require higher current draw. Consider the pinout compatibility if upgrading from legacy designs using similar form-factor transceivers.

Part Context

This part belongs to the ADM230 family of RS-232 transceivers, which are known for their robust performance in noisy environments. The 'LA' suffix typically denotes environmental compliance attributes such as lead-free construction. It is widely used in embedded systems where space and power efficiency are constrained compared to standard industrial-grade alternatives.

Replacement Considerations

Check for pin-compatible alternatives like the ADM202 or ADM203 if fewer channels are sufficient. Verify electrical specifications against the MAX232 series for direct drop-in replacements in existing designs, ensuring voltage levels and drive strengths meet system requirements.
