The LM35DZ/NOPB TO923 is a three terminal temperature sensor designed for direct Celsius temperature measurement with a linear analog output. In a compact TO923 package and with lead (NOPB) construction, this device provides a precise, factory calibrated voltage proportional to ambient temperature with no external calibration required for basic use. Each contains 3 pieces. Key benefits Direct Celsius output: Vout is proportional to temperature with a fixed 10 mV per degree Celsius scale, simplifying interface to microcontrollers and ADCs. Simple wiring: Three terminals (Vout, Gnd, Vs) enable straightforward integration with standard power supplies and measurement circuits. No external signal conditioning: The analog output requires minimal signal processing for temperature reading. Wide operating range: Suitable for environments from 55 C to +150 C with reliable performance. Lead packaging: NOPB variant provides a lead TO923 package for compliant assembly. Compact and robust: TO923 plastic package is small, durable, and well suited for dense PCBs and prototyping. Key attributes Functionality: Threeterminal analog temperature sensor with linear 10 mV/°C output and 0 C corresponding to approximately 0 V. Compatibility: Ideal for direct connection to MCU ADC inputs or data acquisition systems; compatible with common development platforms (Arduino, PIC, STM32, etc.) using standard voltage supplies. Size and packaging: TO923 package, epoxy encapsulated, lead (NOPB). Performance: Factory calibrated for Celsius measurement with a linear response across the specified range; designed for low self heating and reliable operation in a wide temperature span. Pinout (TO92, viewed from the front): Pin 1 Vout, Pin 2 GND, Pin 3 Vs (supply voltage). Specifications snapshot (typical expectations for LM35DZ/NOPB in TO923) Output: 10 mV/°C (Vout proportional to ambient temperature) Temperature range: 55 C to +150 C Supply voltage: 4 V to 30 V Package: TO923, epoxy encapsulated, lead (NOPB) Calibration: Factory calibrated for direct Celsius readings Common use cases Microcontroller based temperature sensing: Connect Vout to an MCU ADC to monitor ambient temperature in projects built on Arduino, Raspberry Pi (via ADC), or other microcontroller platforms. Environmental monitoring: Integrate into data loggers or environmental sensing systems to track ambient temperature with simple hardware and software. Battery and HVAC monitoring: Use as a compact temperature sensor in battery packs, power management, or HVAC control to maintain safe operating conditions. Pinout and connection notes Pin 1: Vout — connect to the analog input of your microcontroller (via a proper ADC channel) Pin 2: GND — connect to circuit ground Pin 3: Vs — connect to a DC supply in the 4 to 30 V range (regulated or unregulated as required by your design) Ensure proper decoupling and consider input filtering if your application is susceptible to noise on the analog line Package contents Quantity: 3 pieces Part: LM35DZ/NOPB Package: TO923, lead This description reflects the LM35DZ/NOPB model in a TO923 package with three units per package and provides practical guidance for typical use while maintaining a professional, clear tone aligned with the product specifications.
