Overview
The LM158AJRQMLV is a military-grade dual operational amplifier manufactured by Texas Instruments. It features two internally compensated amplifiers designed for single-supply operation from 3V to 32V or split supplies of ±1.5V to ±16V. The device provides high DC voltage gain of 100 dB and a unity-gain bandwidth of 1 MHz. It operates within an extended temperature range of -55°C to +125°C. Key electrical specifications include a maximum input offset voltage of 4 mV, a power supply current of 4 mA at 30V, and a common-mode rejection ratio of 70 dB.
Feature Summary
- Radiation hardened design with ELDRS-free capability up to 100 krad(Si)
- Single-supply operation allows direct sensing near ground
- Internally frequency compensated for stability in unity-gain configurations
- Low power drain independent of supply voltage magnitude
Applications
- Transducer amplifiers
- DC gain blocks
- Military and aerospace electronic systems
Procurement Notes
Verify the specific radiation qualification level (High Dose Rate vs. ELDRS Free) required for the application against the ordering suffix. Confirm package type availability as the QMLV designation supports multiple physical packages including TO-99, CDIP, and CFP. Ensure compliance with MIL-STD-883 testing requirements during procurement.
Selection Notes
Select this component when radiation hardness is mandatory for dual op amp circuits. It serves as a drop-in replacement for standard LM158 variants in environments requiring high dose rate tolerance. Consider the specific package constraints and thermal dissipation limits when designing for the full operating temperature range.
Part Context
This part belongs to the LM158QML series, which consists of low-power dual operational amplifiers. The series is specifically engineered for harsh environments where reliability under radiation exposure is critical. It maintains the functional characteristics of the commercial LM158 while adhering to strict military quality standards.
