TL103WIDR

Instrumentation, Op Amps, Buffer Amps Overview

The TL103WIDR is a dual operational amplifier with an integrated voltage reference, manufactured by Texas Instruments. It utilizes a voltage-feedback architecture in an 8-SOIC surface-mount package. Key electrical parameters include a gain-bandwidth product of 900 kHz and a slew rate of 0.4V/µs. The device operates on a single supply voltage ranging from 3 V to 32 V, with a typical supply current of 700µA per channel. It features a maximum input bias current of 20 nA and an input offset voltage of 1 mV. The component supports an operating temperature range of -40°C to +105°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Integrates a precision internal voltage reference alongside dual operational amplifiers within a single compact package.
• Designed for low-power applications with minimal supply current consumption per channel.
• Provides high common-mode rejection ratio for accurate signal processing in single-supply systems.

Instrumentation, Op Amps, Buffer Amps Applications

• Battery-powered instrumentation circuits requiring stable reference voltages.
• Signal conditioning stages in data acquisition systems.
• Active filter implementations in audio or sensor interfaces.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'DR' indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status as REACH compliant and free of lead. Ensure the 8-SOIC footprint matches the PCB layout constraints. Check for any recent PCN updates regarding assembly sites or design changes before finalizing procurement plans.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a combined op-amp and reference solution is needed to reduce board space. Consider the 900 kHz bandwidth for moderate-speed applications rather than high-frequency signals. Evaluate the 0.4V/µs slew rate against required signal transition speeds. Compare power consumption requirements against other dual op-amps if lower current draw is critical.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the TL103 family of dual operational amplifiers with internal references. It shares functional similarities with the TL103WAID but differs in industrial temperature grading and specific electrical tolerances. The device is designed to replace older discrete reference and amplifier combinations in cost-sensitive analog designs.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

TSM103WID from STMicroelectronics is listed as a direct substitute. Verify pin compatibility and electrical parameter alignment before substitution. Other family members like TL103WIDRG4 may offer identical functionality with different packaging or compliance markings.
