Frequently Asked Questions
What supply voltage range does LM158AWG-QMLV support in aerospace single-supply designs?
The LM158AWG-QMLV operates from a single supply of 3 V to 32 V, or a dual supply of ±1.5 V to ±16 V. This flexibility allows the amplifier to run directly from a 5 V or 28 V avionics bus, which is common in military electronics systems requiring stable analog signal processing.
How does the 70 dB CMRR of LM158AWG-QMLV benefit differential signal measurements?
A 70 dB common-mode rejection ratio means the amplifier attenuates common-mode noise by a factor of approximately 3162:1 relative to the differential signal. This high rejection level is critical for accurately amplifying small sensor outputs, such as 10 mV thermocouple signals, in environments with significant electrical interference.
What qualification level does LM158AWG-QMLV carry and why does it matter for space applications?
It is qualified to QML-V, the highest tier of the MIL-PRF-38535 standard, which mandates full wafer-level screening, radiation testing, and lot acceptance testing. This qualification ensures the device meets the reliability requirements for Class V space-level applications, where component failure rates must remain below 1 failure per 10^6 device hours.
For a precision analog filter design, what is the maximum input offset voltage of the LM158AWG-QMLV?
The maximum input offset voltage is 4 mV (4000 µV), which can introduce DC errors in precision signal chains. For designs requiring lower offset, an external trimming resistor network or auto-zero technique can reduce this error to below 100 µV. Understanding this 4 mV worst case is essential when setting gain in multi-stage filter designs.
Which package does LM158AWG-QMLV use and what is the pin count?
The device comes in a 10-pin small outline package (SOIC-10) with a 1.27 mm pin pitch, accommodating both amplifier channels and power supply pins in a compact SMT footprint. The 10-pin SOIC measures approximately 6.2 mm × 3.9 mm, fitting easily on high-density military PCB designs.
