説明
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).

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
