Texas Instruments LM111QML-SP Voltage Comparator LM111J-8RLQMLV

The LM111J-8RLQMLV is a voltage comparator designed for high reliability in radiation-sensitive applications, featuring radiation assurance for high dose rates up to 50 krad(Si) and low dose rates up to 100 krad(Si). It operates from a single 5V supply or dual supplies ranging from ±15V, making it versatile for various circuit designs. The device has a low input current of 200 nA maximum and an offset current of 20 nA maximum over temperature, ensuring minimal impact on the signal being measured. With a differential input voltage range of ±30V, the LM111J-8RLQMLV can handle significant voltage variations. It also includes offset voltage null capability and strobe functionality, enhancing its usability in complex applications. The output is compatible with various logic families, including TTL, DTL, and MOS, and can drive loads up to 50V at 50 mA. The device is slower than some alternatives, with a response time of 200 ns, but is less prone to spurious oscillations, making it suitable for stable applications.
