What are the key features of LM158AJRLQMLV?
- Dual op-amp in 8-pin CDIP rated to ±16 V supply for military-grade high-reliability designs
- Ultra-low bias current of 0.05 µA at 25°C minimizes loading on high-impedance sensor sources
- 80 dB typical CMRR with 65 dB minimum for accurate differential signal amplification
- Voltage-feedback architecture with internal frequency compensation simplifies stable gain configuration
What is LM158AJRLQMLV used for?
The LM158AJRLQMLV is selected for military, aerospace, and high-reliability industrial systems where dual low-power op-amps must operate across extreme temperature ranges on ±16 V supply rails. Its ultra-low 0.05 µA bias current makes it ideal for amplifying signals from high-impedance sources such as photodiodes, piezoelectric sensors, and electrochemical cells. The 8-pin CDIP ceramic package provides hermetic sealing for long-term stability in harsh or radiation-exposed environments.

Frequently Asked Questions
What supply voltage range does LM158AJRLQMLV support, and how does that affect circuit design flexibility?
The LM158AJRLQMLV operates from ±16 V dual supply or up to 32 V single supply, providing designers with broad flexibility across military and industrial power architectures. This wide range allows the same device to function in ±15 V analog systems and 24 V single-rail industrial measurement circuits without requiring separate op-amp SKUs.
How low is the input bias current of LM158AJRLQMLV, and which sensor types benefit most from this specification?
The LM158AJRLQMLV has a maximum input bias current of only 0.05 µA at 25°C, making it ideal for amplifying signals from high-impedance sources such as photodiodes (typically 100 MΩ source impedance), pH electrodes, and piezoelectric sensors. At higher temperatures, the bias current rises slightly to 0.001 µA average, still maintaining negligible loading error.
What CMRR does LM158AJRLQMLV achieve, and why is the minimum spec critical for precision instrumentation?
The LM158AJRLQMLV achieves a typical CMRR of 80 dB with a guaranteed minimum of 65 dB. In precision instrumentation, the minimum CMRR (65 dB) defines the worst-case rejection of common-mode noise from 50 Hz or 60 Hz power lines, which translates to a noise rejection factor of approximately 1775:1 at the specified supply and temperature conditions.
What is the significance of the CDIP package on LM158AJRLQMLV for long-life deployments?
The 8-pin CDIP (Ceramic Dual Inline Package) uses a hermetically sealed ceramic body, which protects the die from moisture ingress, ionic contamination, and radiation effects far better than standard PDIP plastic packages. This hermetic sealing is a requirement for MIL-SPEC and space-grade components expected to operate reliably over 20+ year service lives in satellites, avionics, and downhole sensing equipment.
