Additional Details

The LM6142AMJ-QML operates from a single supply voltage ranging from +2.7V to +24V, or from dual supplies ranging from ±1.35V to ±12V. It features a typical quiescent current of only 340μA per amplifier. The rail-to-rail output swing allows the output voltage to swing close to the positive and negative supply rails, maximizing the usable signal range. The high input impedance and low input bias current minimize loading effects on the signal source, ensuring accurate signal amplification. It is available in a hermetically sealed package (usually a ceramic DIP or flatpack). Thorough testing and screening are performed to ensure compliance with military standards.
