Overview
The KA2904DTF is a dual operational amplifier manufactured by Fairchild Semiconductor, now part of ON Semiconductor. It features two independent, high-gain, internally frequency-compensated amplifiers designed for single power supply operation over a wide voltage range. The device operates from 3V to 26V (or ±1.5V to ±13V). Key electrical characteristics include a large DC voltage gain of 100dB and an input common mode voltage range that includes ground. The output voltage swing extends from 0V DC to Vcc - 1.5V DC.
Feature Summary
- Internally frequency compensated for unity gain stability
- Wide power supply range suitable for battery operation
- Input common mode voltage range includes ground potential
- Large output voltage swing capability
Applications
- Transducer amplifier circuits
- DC gain blocks
- Single power supply OP-AMP systems
Procurement Notes
Verify the manufacturer status as Fairchild Semiconductor has been integrated into ON Semiconductor. Confirm the specific ordering suffix matches the required package and temperature grade. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability. Check for RoHS compliance documentation if required for your assembly process.
Selection Notes
Select this component when a dual op-amp with internal frequency compensation is required for single-supply applications. It is suitable for designs needing a wide operating voltage range and low power drain. Consider the TO-220 or similar through-hole package availability if board space permits. Verify that the 1MHz bandwidth meets the signal processing requirements.
Part Context
The KA2904DTF belongs to the LM2904 family of dual operational amplifiers. This series is widely used in general-purpose analog circuits. Fairchild Semiconductor was acquired by ON Semiconductor, which continues to produce these devices under the onsemi brand. The part is commonly found in industrial and commercial electronic equipment requiring reliable amplification.
Replacement Considerations
LM2904 variants from other manufacturers may serve as direct replacements. Verify pin compatibility and electrical specifications before substitution. ON Semiconductor offers equivalent parts within their portfolio.
