Features • Small SOT23-5 package saves space • Shutdown mode conserves power between temperature readings • Operates over a full -40°C to +150°C range • SPI and MICROWIRE Bus interface Description The LM95071 is a low-power, high-resolution digital temperature sensor with an SPI and MICROWIRE compatible interface, available in the 5-pin SOT23. The host can query the LM95071 at any time to read temperature. Its low operating current is useful in systems where low power consumption is critical. The LM95071 has 13-bit plus sign temperature resolution (0.03125°C per LSB) while operating over a temperature range of -40°C to +150°C. The LM95071's 2.4V to 5.5V supply voltage range, fast conversion rate, low supply current, and simple SPI interface make it ideal for a wide range of applications.

Reliability Metrics

Part Number	Process	EFR Reject	EFR Sample Size	PPM	LTA Rejects	LTA Device Hours	FITS	MTTF (Hours)
LM95071CIMF	CMOS7	0	18406	0	0	1089000	4	309006723

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
