The typical calibration accuracy of the LM335AH is ±1°C at 25°C, but it can vary up to ±2°C over the entire operating temperature range.
To ensure accuracy, it's essential to provide a stable voltage supply, minimize noise and interference, and use a high-impedance input buffer amplifier to prevent loading the output.
Yes, the LM335AH can be used in a ratiometric configuration, which can provide better accuracy and reduce the effects of supply voltage variations.
A high-input-impedance, low-offset voltage amplifier like the OP07 or OP1177 is recommended as an output buffer amplifier to prevent loading the output and ensure accuracy.
The output voltage offset can be handled by using an offset correction circuit or by calibrating the system to account for the offset, which is typically around 400 mV.
