Key Features
- Linear analog output with 10 mV/°C gain and 600 mV DC offset enables simple single-supply temperature measurement from -30°C to 100°C
- Ultra-low 125 µA supply current and 0.2°C self-heating make it ideal for battery-powered and space-constrained remote sensing
- Wide 2.7V to 10V supply range with factory-calibrated accuracy of ±2°C at 25°C eliminates external calibration
- TO-92 through-hole package provides robust mechanical mounting for industrial and field applications
Applications
The LM61CIZ/NOPB is widely used in HVAC systems, battery-powered environmental monitors, and industrial process control where simple analog temperature reading is preferred. Its low power consumption and wide supply range suit remote sensor nodes and portable instruments. The linear voltage output interfaces directly with ADCs in microcontroller-based designs without complex signal conditioning.

Frequently Asked Questions
What is the output voltage formula for the LM61CIZ/NOPB?
The LM61CIZ/NOPB outputs a linear voltage proportional to temperature with the formula Vout = (10 mV/°C × T) + 600 mV. At 25°C the output is 850 mV, at 0°C it is 600 mV, and at 100°C it reaches 1600 mV. The 600 mV offset allows reading negative temperatures down to -30°C without requiring a negative supply rail.
What is the accuracy and temperature range of the LM61CIZ/NOPB?
The LM61CIZ/NOPB measures temperatures from -30°C to 100°C. It provides ±2°C typical accuracy at 25°C, ±3°C maximum over the -25°C to 85°C range, and ±4°C maximum across the full -30°C to 100°C operating range. Nonlinearity is limited to ±0.8°C maximum.
What supply voltage does the LM61CIZ/NOPB require?
The LM61CIZ/NOPB operates from a single supply between 2.7V and 10V, drawing only 125 µA maximum at 25°C. This ultra-low current consumption produces just 0.2°C of self-heating in still air, making it suitable for battery-powered applications and remote sensor nodes where power budget is critical.
What are common alternatives to the LM61CIZ/NOPB?
Common alternatives include the TI LM35 which offers higher accuracy with a 10 mV/°C output but no negative temperature offset, the TMP36 from Analog Devices with a similar 750 mV offset at 25°C, and the TI LM61BIZ/NOPB which is a tighter-tolerance version of the same LM61 family. For digital output, the TMP102 provides I2C interface with ±0.5°C accuracy.
What package options are available for the LM61 and how does the TO-92 variant compare?
The LM61 is available in TO-92 (LM61CIZ/NOPB) and SOT-23 (LM61CIM3/NOPB) packages, both with 3 pins. The TO-92 package at 19.14 mm² offers easier hand-soldering and robust through-hole mounting for prototyping and industrial applications. The SOT-23 at 6.92 mm² is preferred for surface-mount, space-constrained PCB designs.
