Overview
The LF412MH/NOPB is a military-grade dual operational amplifier from the LF412 series, manufactured by Texas Instruments. It utilizes BiFET technology to deliver high-speed performance with a gain-bandwidth product of 3 MHz and a slew rate of 15 V/µs. The device features low input bias current of 200 pA and low input offset voltage of 3 mV. It operates within a supply voltage range of ±5 V to ±18 V (10 V to 36 V single supply) and supports through-hole mounting in a TO-99-8 metal can package. The component is rated for an extended operating temperature range from -55°C to +125°C.
Feature Summary
- Military-grade qualification ensuring reliability in harsh environments
- BiFET input stage providing low noise and low input bias current
- High slew rate suitable for fast signal processing applications
Applications
- Precision instrumentation requiring high stability
- Medical equipment demanding strict reliability standards
- Aerospace and defense electronic systems
Procurement Notes
Verify the specific suffix 'MH' confirms military-grade qualification and the 'NOPB' indicates lead-free status. Confirm the TO-99-8 package type matches your mechanical constraints. Ensure the supplier provides traceability documentation required for military specifications. Check for RoHS compliance declarations if applicable to your assembly process requirements.
Selection Notes
Select this component when military reliability and wide temperature operation are mandatory. The BiFET input offers superior bias current characteristics compared to standard bipolar op-amps. Consider the TO-99-8 package for hermetic sealing needs. Compare against commercial variants like LF412CN if environmental ratings do not require military grade.
Part Context
This part belongs to the LF412 family of dual JFET-input operational amplifiers known for high speed and low power consumption. The LF412MH/NOPB specifically targets ruggedized applications where standard commercial parts may fail due to extreme temperatures or vibration. It serves as a robust alternative to older discrete FET amplifier designs in critical signal chains.
Replacement Considerations
Direct substitutes include other military-qualified dual JFET op-amps such as the LM412MH. Verify pinout compatibility and electrical parameter margins before substitution. Commercial equivalents like LF412CN lack the necessary temperature and reliability ratings for direct replacement in military contexts.
