FM51
Description
The FM51 is a high-precision CMOS temperature sensor that provides a cost-effective solution for applications requiring highaccuracy temperature monitoring. The FM51 is ideally suited for applications requiring high drive current. The FM51 output voltage ramp is extremely linear and has a slope of 10m V/°C. It is typically accurate to ±1°C over a temperature range of -40°C to 125°C and has a typical room temperature accuracy of ±0.5°C. The output voltage characteristic for the FM51 is illustrated in Figure 1.
The FM51 does not require external calibration. Factory calibration of the FM51 is performed using a low-cost trimming technique.
The FM51 is available in 3-pin SOT-23 surface mount packages.
