MAX3120CSA+T

Overview

The MAX3120CSA+T 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 only 120µA during active operation and features a 10nA shutdown mode to extend battery life. It requires minimal external components, specifically a photodiode, an infrared LED, and a current-setting resistor. The component is housed in an 8-pin SO package and operates within a temperature range of 0°C to +70°C.

Procurement Notes

Verify the specific suffix '+T' against official manufacturer documentation to confirm tape-and-reel packaging status, as standard datasheets may list bulk tube options. Ensure the 'C' designation aligns with the required commercial operating temperature range of 0°C to +70°C for your specific application environment.

Selection Notes

Select this component when designing low-profile infrared communication links that require minimal board space and extended battery life. Consider the need for external optical components like the Temic BPV22NF photodiode or Hewlett Packard HSDL-4220 IR LED to meet specific distance and data rate requirements.
