KA258

Overview

The onsemi KA258 is a dual operational amplifier featuring two independent, high-gain, internally frequency-compensated circuits. Designed for single-supply operation, it supports a wide power supply range of 3V to 32V (or ±1.5V to ±16V). The device includes an input common-mode voltage range that extends to ground and provides a large output voltage swing from 0V DC to Vcc - 1.5V DC. It maintains low power drain suitable for battery applications.

Feature Summary

Internally frequency compensated for unity gain stability
Input common-mode voltage range includes ground potential
Large output voltage swing capability down to 0V DC
Low power supply current drain independent of voltage magnitude

Applications

Transducer amplifiers
DC gain blocks
Single power supply operational amplifier circuits

Procurement Notes

Verify the specific package variant required, as the KA258 series is available in 8-DIP, 8-SOP, and 9-SIP configurations. Confirm the operating temperature grade matches the design requirements, distinguishing between the standard KA258 (-25°C to +85°C) and the KA258A variant. Ensure the selected part number suffix corresponds exactly to the desired physical footprint and thermal rating.

Selection Notes

Select the KA258 when a dual op-amp requires ground-referenced input capabilities within a single-supply architecture. The internal frequency compensation simplifies circuit design by ensuring stability in unity-gain configurations without external components. Consider the KA258A variant if tighter input offset voltage specifications are necessary for precision signal conditioning tasks.

Part Context

The KA258 belongs to a family of dual operational amplifiers originally developed by Fairchild Semiconductor, now distributed by onsemi. This series shares functional similarities with other industry-standard dual op-amps but is distinguished by its specific electrical characteristics and packaging options including DIP, SOP, and SIP formats designed for various mounting styles.
