Overview
The KA2904DMTF is a dual operational amplifier manufactured by onsemi, housed in a SOP-14 surface-mount package. It features four channels with an input offset voltage of 7 mV and an input bias current of 250 nA. The device operates on a single supply from 3 V to 26 V or dual supplies from 1.5 V to 13 V. Quiescent current per channel is 1.2 mA, delivering 13 mA output current. Common-mode rejection ratio and power supply rejection ratio are both 50 dB. Operating temperature range spans from -40 °C to +85 °C.
Feature Summary
- Dual operational amplifier architecture providing two independent signal processing channels within a compact surface-mount footprint.
- General-purpose design optimized for standard analog signal conditioning tasks requiring moderate bandwidth and drive capability.
- Operates reliably across extended industrial temperature ranges suitable for diverse environmental conditions.
Applications
- Signal conditioning circuits
- Active filtering applications
- Sensor interface amplification
Procurement Notes
Verify component authenticity through authorized distribution channels due to obsolete status. Confirm RoHS compliance details via official documentation before integration. Ensure storage conditions prevent moisture damage given the SOP-14 packaging type. Validate pin compatibility with existing PCB layouts during replacement planning.
Selection Notes
Select this component for general-purpose analog applications requiring dual amplification without shutdown functionality. Consider the 7 mV offset voltage and 50 dB CMRR specifications for precision requirements. Evaluate the 13 mA output drive against load demands. Verify that the SOP-14 package fits available board space constraints.
Part Context
This part belongs to the KA2904 series of dual operational amplifiers produced by onsemi. It serves as a surface-mount variant designed for modern electronics manufacturing processes. The device complements other general-purpose op-amps in the manufacturer's portfolio for cost-sensitive analog designs.
Replacement Considerations
Check for direct pin-compatible substitutes within the same family. Verify electrical parameter equivalence for critical performance metrics. Assess availability of active alternatives if long-term supply stability is required.
