Overview
The KA358DTF is a dual operational amplifier manufactured by onsemi, featuring a wide single-supply voltage range of 3.0 V to 32 V and a corresponding dual supply range of ±1.5 V to ±16 V. It operates with a typical quiescent current of 0.7 mA per amplifier and supports a slew rate of 0.5 V/µs. The device includes internal frequency compensation, short-circuit protection, and an input common-mode voltage range that extends to the negative rail. It is housed in a compact SOT-23-5 surface-mount package.
Feature Summary
- Dual operational amplifier architecture with integrated frequency compensation
- Wide single-supply operating voltage range from 3.0 V to 32 V
- Internal short-circuit protection for output stages
- Input common-mode voltage range includes the negative supply rail
Applications
- Transducer amplification
- Active filters
- DC gain blocks
Procurement Notes
Verify the specific suffix 'DTF' against the manufacturer's official datasheet to confirm the exact tape-and-reel quantity and packaging specifications. Ensure the component meets RoHS compliance requirements if applicable to your manufacturing process. Cross-reference the ordering part number with authorized distributors to confirm current availability and lifecycle status.
Selection Notes
Select this component when a low-cost, general-purpose dual op-amp is required for single-supply applications. It is suitable for designs needing operation down to 3.0 V without requiring dual rails. Consider the SOT-23-5 package constraints for PCB layout and thermal management. Verify that the 0.5 V/µs slew rate meets the signal bandwidth requirements of the application.
Part Context
The KA358 series belongs to the industry-standard 358 family of dual operational amplifiers. This specific variant integrates standard features such as short-circuit protection and wide supply voltage tolerance into a small surface-mount footprint. It serves as a direct functional replacement for legacy through-hole packages in modern compact electronic designs.
Replacement Considerations
Compatible replacements include the LM358, TL082 (note: JFET input differences), and MC34078. Verify pinout compatibility and electrical parameter alignment before substitution.
