ADM3202ARN

Drivers, Receivers, Transceivers Overview

The ADM3202ARN is a low-power, dual-channel RS-232 transceiver designed for single 3.3 V power supplies. It supports data rates up to 460 kbps and meets EIA-232E specifications. The device incorporates an internal charge pump requiring four external 0.1 μF capacitors to generate ±6.6 V levels. It features Schmitt-trigger receivers with 0.4 V hysteresis and internal 5 kΩ pull-down resistors on inputs. The component provides IEC 1000-4-2 (801.2) ESD protection of ±8 kV contact and ±15 kV air gap discharge on RS-232 pins. Operating voltage ranges from 3.0 V to 5.5 V, with a typical supply current of 3 mA at no load.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump voltage converter generates required RS-232 levels from a single 3.3 V supply using minimal external components.
• High slew rate capability allows reliable data transmission at rates up to 460 kbps while minimizing electromagnetic interference.
• Receivers include Schmitt-trigger inputs with defined hysteresis to ensure error-free reception under noisy conditions or slow signal transitions.
• Built-in electrostatic discharge protection on serial pins enhances reliability in portable and industrial environments.

Drivers, Receivers, Transceivers Applications

• General-purpose RS-232 data links
• Portable instruments and battery-powered devices
• Printers and palmtop computers

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official guide to confirm package type and compliance status. The 'N' suffix indicates a narrow body SOIC package, while 'Z' denotes RoHS compliance. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity and traceability for this Analog Devices component.

Drivers, Receivers, Transceivers Selection Notes

Select the ADM3202ARN when a dual-channel RS-232 interface is required without shutdown functionality. Unlike the ADM3222, this variant lacks enable and shutdown pins, making it suitable for always-on applications. It serves as a direct upgrade for legacy MAX3222/MAX3232 designs operating at 3.3 V. Consider alternative packages if space constraints require thin shrink or wide body options.

Drivers, Receivers, Transceivers Part Context

The ADM3202 belongs to the ADM3202/ADM3222/ADM1385 family of low-power RS-232 line drivers and receivers. These devices are enhancements of the AD230 to AD241 series, offering plug-in compatibility with improved performance at lower voltages. The family shares core architecture but differs in control features, such as the shutdown capabilities found in the ADM3222 and ADM1385 variants.

Drivers, Receivers, Transceivers Replacement Considerations

The ADM3202 is documented as an upgrade for MAX3222, MAX3232, and LTC1385. When replacing these parts, verify that the original design does not utilize the shutdown or enable pins present in those counterparts, as the ADM3202 lacks these control inputs.
