Overview
The MAX3120EUA+ is an IrDA 1.2-compatible infrared transceiver designed for battery-powered, space-constrained applications. It operates on a single +3V to +5.5V supply and supports data rates from 2.4kbps to 115.2kbps. The device consumes 120µA during operation and features a 10nA shutdown mode. It includes a high-current LED driver capable of sinking 200mA with less than 2Ω on-resistance. The component is housed in an 8-pin µMAX package and functions within a temperature range of -40°C to +85°C.
Feature Summary
- IrDA 1.2 compatible infrared transceiver optimized for low-power portable devices
- Integrated high-power LED driver supporting up to 200mA drive current
- Ultra-low power consumption with 10nA shutdown mode for extended battery life
- Requires minimal external components including photodiode, IR LED, and resistor
Applications
- Personal Digital Assistants (PDAs)
- Palmtop Computers
- Cell Phones
- Hand-Held Equipment
- Peripherals
Procurement Notes
Verify the ordering suffix 'EUA+' indicates the Extended temperature range (-40°C to +85°C) and lead-free/ROHS compliance. Confirm the package type matches the required board space constraints, as the µMAX package occupies half the area of an 8-pin SO variant. Ensure compatibility with the specific system voltage requirements between 3V and 5.5V.
Selection Notes
Select this component when designing systems requiring IrDA 1.2 compliance with strict space limitations. The µMAX package is suitable for dense layouts where board real estate is critical. Consider the 200mA LED drive capability against the specific forward current requirements of the chosen infrared LED to ensure adequate optical output without exceeding thermal limits.
Part Context
The MAX3120 is part of Maxim Integrated's family of low-profile infrared transceivers. It serves as a direct replacement for older discrete IR solutions or competing transceivers that require more external circuitry. The device integrates both the transmitter and receiver functions into a single chip, simplifying the design process for short-range wireless communication interfaces.
Replacement Considerations
The MAX3120CUA+ offers identical functionality but is rated for the Commercial temperature range (0°C to +70°C). Verify if the application environment requires the Extended temperature range provided by the 'E' suffix before substituting.
