Overview
The CA0258M is a dual operational amplifier manufactured by Harris Corporation, belonging to the CA3240 series. It features a maximum input offset voltage of 9000 uV and operates within a supply voltage range up to 32 V. The device utilizes a bipolar process and is housed in an 8-pin PDIP package with a 2.54 mm pin spacing. Designed for commercial temperature ranges from 0°C to 70°C, it provides two independent amplifiers per unit.
Feature Summary
- Dual operational amplifier configuration providing two independent signal processing channels
- Bipolar manufacturing process ensuring stable performance characteristics
- Standard DIP-8 through-hole packaging for easy integration into printed circuit boards
Applications
- General-purpose analog signal conditioning circuits
- Audio pre-amplification stages
- Sensor interface applications requiring low offset voltage
Procurement Notes
Verify the manufacturer origin carefully, as Intersil (now Renesas) acquired Harris Semiconductor assets. Confirm that the specific CA0258M suffix corresponds to the intended package and temperature grade. Ensure compatibility with existing board layouts designed for standard DIP-8 footprints before procurement.
Selection Notes
Select this component when a dual op-amp with moderate precision is required. The 9 mV max offset voltage suits general applications but may require trimming for high-precision instrumentation. Consider the 32 V maximum supply limit and commercial temperature range constraints during system design.
Part Context
This part belongs to the CA3240 family of dual operational amplifiers. Harris Corporation was a prominent semiconductor manufacturer before its acquisition by Intersil. These devices are widely used in industrial and consumer electronics for basic analog signal processing tasks.
Replacement Considerations
Check for equivalents such as the CA3240AE or LM358 variants. Verify pinout compatibility and electrical parameter overlaps, particularly regarding input offset voltage and supply voltage limits, to ensure functional interchangeability.
