KA258AD

Overview

The KA258AD is a dual general-purpose operational amplifier manufactured by onsemi, housed in an 8-SOIC surface-mount package. It features two independent circuits within a single component. The device operates with a supply voltage range of 3 V to 32 V and supports a maximum output current of 30 mA per channel. Key electrical specifications include a typical input bias current of 40 nA, an input offset voltage of 1 mV, and a quiescent supply current of 800 µA. The unit is rated for operation between -25°C and 85°C.

Feature Summary

Dual-channel architecture providing two independent operational amplifiers in one package
Wide single-supply voltage capability supporting low-voltage to high-voltage applications
Low power consumption suitable for battery-operated systems
High input impedance characteristics minimizing loading effects

Applications

Signal conditioning in industrial sensor interfaces
Active filtering circuits requiring dual amplification stages
Transducer signal processing in automotive environments
General-purpose analog computation tasks

Procurement Notes

Verify the obsolete status of this part number before design finalization. Confirm availability through authorized distributors or check for qualified replacement components such as LM258DR2G. Ensure that any substitute maintains compatibility with the required 8-SOIC footprint and electrical parameters to avoid redesign efforts.

Selection Notes

Select this component when dual op-amp functionality is required in a compact surface-mount form factor. Consider the wide supply voltage range and low bias current for precision applications. Evaluate thermal performance within the specified operating temperature range. Verify that the 30 mA output drive capability meets load requirements without external buffering.

Part Context

This device belongs to the KA258 series of dual operational amplifiers produced by onsemi. It shares functional similarities with other industry-standard dual op-amps but is distinguished by its specific pinout and packaging configuration. The series is designed for cost-effective analog signal processing in consumer and industrial electronics.
