Overview
The Texas Instruments 8102306CA is a military-grade, quad JFET-input operational amplifier housed in a 14-CDIP package. It operates within a supply voltage range of up to 30 V and features a bandwidth of 3 MHz with a high slew rate of 13 V/us. The device supports an extended temperature range from -55°C to 125°C. Marked as TL074MJB, it provides low-noise performance suitable for demanding analog signal processing applications requiring high input impedance and stability under extreme conditions.
Feature Summary
- Military-grade qualification ensuring reliability in harsh environments
- JFET input stage providing high input impedance and low noise characteristics
- Quad configuration integrating four independent amplifiers in a single package
- High slew rate capability for fast signal response
Applications
- Precision instrumentation systems requiring military reliability
- Low-noise audio and video signal conditioning circuits
- Industrial control systems operating in extreme temperatures
- Test and measurement equipment requiring high-speed amplification
Procurement Notes
Verify the marking TL074MJB on the component body to confirm authenticity. Ensure the package type matches the required 14-CDIP footprint for your design. Confirm that the military-grade specification meets your project's environmental standards. Check for any specific handling requirements associated with ceramic dual in-line packages during assembly.
Selection Notes
Select this component when military-grade reliability and low-noise performance are critical. The JFET input offers higher impedance than bipolar alternatives. Consider the 14-CDIP package constraints for PCB layout. Verify that the 3 MHz bandwidth and 13 V/us slew rate meet your signal frequency requirements. Ensure the -55°C to 125°C temperature range aligns with your operational environment.
Part Context
This part belongs to the TL07xx series of low-noise JFET-input operational amplifiers. The 8102306CA designation specifically indicates the military-grade variant with enhanced durability. It shares functional similarities with commercial counterparts but includes stricter manufacturing controls and testing procedures to withstand severe environmental stresses.
Replacement Considerations
Cross-reference with other military-grade quad JFET op-amps if availability is limited. Ensure pin compatibility and electrical specifications match closely. Verify that alternative components meet the same temperature and voltage ratings.
