Frequently Asked Questions
What is the output voltage range of the LM94CIMT?
The LM94CIMT produces an analog output voltage that varies linearly with temperature. At 25°C the output is approximately 1.395V with a typical sensitivity of -11.77mV/°C, giving a full output range across its -55°C to +130°C operating temperature span.
What supply voltage does the LM94CIMT require?
The LM94CIMT operates from a single supply voltage between 1.5V and 5.5V, making it compatible with 3.3V and 5V logic systems as well as single-cell battery applications. Its typical quiescent current is only 8.5µA, ideal for low-power and portable designs.
What package does the LM94CIMT come in?
The LM94CIMT is available in a 5-pin SC70 (SOT-323) surface-mount package, offering a very compact footprint for space-constrained PCB layouts in consumer electronics, wearables, and industrial sensor modules.
What are typical applications for the LM94CIMT?
The LM94CIMT is commonly used in HVAC systems, industrial temperature monitoring, automotive cabin sensing, battery-powered portable devices, medical equipment, and PCB thermal management. Its linear analog output simplifies integration with microcontroller ADC inputs without requiring complex digital communication protocols.
How accurate is the LM94CIMT temperature measurement?
The LM94CIMT offers a typical accuracy of ±2°C over the -55°C to +130°C temperature range. This precision, combined with its low offset and low noise characteristics, makes it suitable for applications requiring reliable and repeatable temperature readings without additional calibration in many use cases.
