Overview
The KA1458DTF is a dual general-purpose operational amplifier manufactured by onsemi, formerly Fairchild Semiconductor. It features internal frequency compensation and short-circuit protection without requiring external components. The device supports an operating temperature range of 0°C to +70°C and utilizes an 8-SOP surface-mount package. Electrical characteristics include a typical slew rate of 0.5 V/µs, input bias current up to 1000 nA, and supply current of 2.3 mA per amplifier.
Feature Summary
- Internal frequency compensation eliminates the need for external components
- Short circuit protection safeguards against output faults
- High common mode voltage range suitable for voltage follower applications
- Latch-up free operation ensures stable performance
Applications
- Voltage followers
- Integrator circuits
- Summing amplifiers
- General feedback applications
Procurement Notes
Verify that the specific suffix DT indicates the 8-SOP package variant as documented in the ordering information. Confirm the manufacturer origin aligns with onsemi or Fairchild Semiconductor legacy documentation. Ensure the component meets the specified commercial temperature range requirements for the target application environment.
Selection Notes
Select this component when a dual op-amp with integrated frequency compensation is required. The absence of latch-up makes it preferable over older designs for single-supply or wide-range voltage applications. Verify that the 8-SOP package dimensions fit the available PCB footprint constraints.
Part Context
This part belongs to the KA1458 series of dual operational amplifiers. The series includes variants such as the KA1458D (8-SOP) and KA1458S (9-SIP). The KA1458DTF specifically denotes the surface-mount SOP version designed for automated assembly processes while maintaining the electrical specifications of the standard series.
Replacement Considerations
Direct substitutes include other dual op-amps from the same family such as the KA1458D. Cross-reference pinouts and package dimensions carefully when replacing with generic equivalents to ensure compatibility with existing board layouts.
