ADM209AR

Overview

The ADM209AR is a dual transmitter and dual receiver RS-232 line driver/receiver manufactured by Analog Devices Inc. It operates from a single +5 V power supply using internal charge pumps to generate the required ±10 V levels for EIA-232-E and V.28 interfaces. The device features two drivers and two receivers, with output voltages swinging to ±10 V. It includes built-in protection against latch-up and offers low power consumption suitable for battery-operated equipment. The component is designed for applications where ±12 V supplies are unavailable.

Feature Summary

Internal charge pump voltage conversion eliminates external capacitors for generating negative supply rails
Single +5 V power supply operation simplifies system design
Built-in latch-up protection ensures reliable operation under fault conditions
Low power consumption mode supports battery-powered applications

Applications

EIA-232-E communication interface circuits
V.28 serial communication ports
Battery-powered handheld devices requiring RS-232 connectivity
Industrial control systems with limited power supply options

Procurement Notes

Verify the specific suffix (e.g., ARZ) for RoHS compliance status when ordering. Confirm package type availability matches design requirements. Check manufacturer documentation for latest revision details before finalizing procurement specifications.

Selection Notes

Select this component when designing RS-232 interfaces requiring only two drivers and receivers. It is appropriate for space-constrained PCB layouts due to minimal external component count. Consider alternative models if higher data rates or additional channel counts are needed.

Part Context

The ADM209AR belongs to the ADM2xx series of RS-232 transceivers from Analog Devices. This family provides solutions for serial communication without requiring dual polarity power supplies. The device serves as a direct upgrade replacement for older MAX205-MAX211 series components in existing designs.

Replacement Considerations

The ADM209AR is documented as a direct upgrade replacement for MAX205 through MAX211 devices. Verify pin compatibility and electrical characteristics match when substituting into legacy designs.
