ADM3202ARNZ

Drivers, Receivers, Transceivers Overview

The ADM3202ARNZ is a low-power, dual-channel RS-232/V.28 line driver and receiver manufactured by Analog Devices Inc. Designed for single 3.3 V power supplies, it operates within a voltage range of 3.0 V to 5.5 V with a typical quiescent current of 3 mA at no load. The device supports data rates up to 460 kbps and conforms to EIA-232E specifications. It features internal charge pumps requiring four external 0.1 μF capacitors to generate ±6.6 V levels. The component includes ESD protection on RS-232 pins rated at ±8 kV contact discharge and ±15 kV air gap discharge per IEC 1000-4-2 (801.2). It is housed in a 16-lead Standard Small Outline Package (SOIC_N) and functions across an industrial temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrates CMOS technology for minimal power dissipation suitable for battery-powered applications
• Provides high slew rate transmission capabilities while maintaining EMI interference minimization
• Includes Schmitt-trigger receivers with hysteresis for error-free reception of noisy inputs
• Features internal pull-down resistors on receiver inputs to ensure defined logic states

Drivers, Receivers, Transceivers Applications

• General-purpose RS-232 data links
• Portable instruments
• Printers and palmtop computers
• Personal Digital Assistants (PDAs)

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant against the ordering guide, as the base model number corresponds to multiple physical packages including SOIC_N, SOIC_W, TSSOP, and SSOP. Confirm RoHS compliance status indicated by the Z suffix if required. Ensure the selected part matches the required lead configuration and thermal characteristics for the intended PCB layout.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a 3.3 V supply is available and shutdown functionality is not required, unlike the ADM3222 or ADM1385 variants. Verify that the application does not exceed the maximum data rate of 460 kbps under worst-case loading conditions. Ensure the design accommodates the necessary external 0.1 μF capacitors for the charge pump circuitry to function correctly.

Drivers, Receivers, Transceivers Part Context

The ADM3202 is part of a family that includes the ADM3222 and ADM1385, which offer additional shutdown and enable features. It serves as an upgrade for older MAX3222/MAX3232 and LTC1385 devices. The device is essentially plug-in compatible with previous generations while providing enhanced performance at lower voltages.

Drivers, Receivers, Transceivers Replacement Considerations

ADM3222ARNZ offers similar electrical characteristics but includes enable and shutdown control pins. ADM1385ARWZ provides driver disable and complete shutdown modes. Both alternatives require verification of pin compatibility and package dimensions before substitution.
