Frequently Asked Questions
What is the output voltage range of the LM61CIM3/NOPB?
The LM61CIM3/NOPB produces a linear analog output of 10mV per °C. At 25°C the output is 600mV (600mV = 10mV/°C × 25°C + 424mV offset). Over the full −10°C to +125°C operating range the output spans approximately 324mV to 1674mV, making it easy to interface directly with a microcontroller ADC.
What supply voltage does the LM61CIM3/NOPB require?
The LM61CIM3/NOPB operates from a single supply voltage between 2.7V and 10V, drawing a maximum quiescent current of 125µA. This wide voltage range and ultralow current consumption make it an excellent choice for 3.3V, 5V, and battery-powered systems.
What package does the LM61CIM3/NOPB come in, and is it RoHS compliant?
The LM61CIM3/NOPB is housed in a 3-pin SOT-23 surface-mount package with a body length of 2.92mm and height of 0.93mm. The NOPB suffix indicates it is lead-free and RoHS compliant (JESD-609 Code e3), suitable for modern green manufacturing processes.
What are common applications for the LM61CIM3/NOPB?
The LM61CIM3/NOPB is used in HVAC systems, industrial process monitoring, battery-powered portable devices, IoT sensor nodes, consumer electronics thermal management, and PC motherboard temperature sensing. Its ±3°C accuracy and linear output eliminate the need for signal conditioning in many low-to-medium precision applications.
What are suitable alternatives to the LM61CIM3/NOPB?
Common alternatives include the LM61BIM3/NOPB (±2°C accuracy, same SOT-23 package), the TMP36 from Analog Devices (similar 10mV/°C transfer function), and the MCP9700 from Microchip (19.5mV/°C, SOT-23). For higher accuracy applications consider the LM75 or TMP102 with digital I2C output.
