KA2902DTF

Overview

The KA2902DTF is a quad general-purpose operational amplifier manufactured by Fairchild Semiconductor, now part of onsemi. It features a bipolar input stage housed in a 14-pin SOP package. The device operates within a supply voltage range of 3V to 26V single supply or ±1.5V to ±13V dual supply. Key electrical characteristics include a maximum input offset voltage of 10mV and an input bias current of 40nA. It provides a gain-bandwidth product of approximately 1MHz and a slew rate suitable for standard signal conditioning applications.

Feature Summary

• Quad configuration integrating four independent general-purpose amplifiers in a single package
• Bipolar input technology ensuring stable performance across wide temperature ranges
• Wide single and dual power supply compatibility for flexible system integration

Applications

• General-purpose analog signal conditioning circuits
• Voltage follower and buffer stages
• Active filter implementations

Procurement Notes

Verify the manufacturer source carefully as Fairchild Semiconductor operations were acquired by onsemi. Confirm the specific suffix 'DTF' matches the required tape and reel packaging format. Ensure the component date code aligns with project lifecycle requirements given potential legacy status variations between original Fairchild and current onsemi production runs.

Selection Notes

Select this component when a quad op-amp solution is required with moderate precision and low cost. It serves as a direct pin-compatible alternative to the LM324 family. Consider input bias current and offset voltage specifications against application requirements. Verify thermal dissipation capabilities within the SOP-14 package for the intended operating environment.

Part Context

This component belongs to the KA2902 series of quad operational amplifiers. It shares functional similarities with industry-standard LM324 devices. The 'DTF' suffix typically denotes a specific tape and reel packaging variant for surface-mount assembly. It represents a legacy product line originally from Fairchild Semiconductor.
