LTC2803IGN-1#PBF

Drivers, Receivers, Transceivers Overview

The LTC2803IGN-1#PBF is a dual RS-232 transceiver manufactured by Analog Devices Inc. It operates on a supply voltage range of 1.8V to 5.5V and features two drivers and two receivers. The maximum data rate is 250kbps for a 1nF/3kΩ load and 100kbps for a 2.5nF/3kΩ TIA/EIA-232-F load. The device includes an integrated DC-to-DC converter generating VDD and VEE supplies. Shutdown mode current is 1µA, while the Receivers Active mode draws 15µA. It is housed in a 16-lead narrow SSOP package with an operating temperature range from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated DC-to-DC converter generates internal power supplies for driving RS-232 levels without external charge pumps.
• Logic supply pin allows independent interfacing with various logic levels ranging from 1.8V to 5.5V.
• Low-power modes include shutdown (1µA) and receivers-active (15µA) to extend battery life.
• Driver outputs are protected against overload and can withstand short circuits to ground or ±15V.

Drivers, Receivers, Transceivers Applications

• Battery-powered systems requiring low quiescent current
• Computers and consumer electronics with RS-232 interfaces
• Diagnostic ports for industrial equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix IGN-1 corresponds to the required industrial temperature grade (-40°C to +85°C) and SSOP-16 package variant. Ensure compliance with RoHS directives as indicated in official documentation before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual-channel RS-232 interface is needed with independent logic voltage support. It is suitable for applications where power consumption must be minimized during idle states. Verify that the required data rate does not exceed 250kbps under standard capacitive loads. Ensure the system design accommodates the external inductor and capacitors required for the internal switching regulator.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2801/LTC2802/LTC2803/LTC2804 family of single and dual RS-232 transceivers. The IGN-1 designation specifically identifies the industrial temperature grade version packaged in a narrow SSOP-16 format. It shares architectural similarities with the DFN variants but offers a different footprint for PCB layout constraints.

Drivers, Receivers, Transceivers Replacement Considerations

The LTC2803CGN-1#PBF serves as a commercial grade alternative within the same package and pinout configuration. Other family members like the LTC2804 offer higher speed capabilities but may require different thermal management considerations.
