TMP36FS

TMP36FS Description

The TMP36FS from Analog Devices Inc. is a precision analog voltage output temperature sensor designed for surface-mount applications. Operating within a 2.7V to 5.5V supply range, it delivers a linear 10mV/°C output with an accuracy of ±2°C (at room temperature) and ±3°C across its full -40°C to +125°C range. Housed in an 8-SOIC package, this sensor is ideal for embedded systems requiring reliable, low-power temperature monitoring. Although marked as obsolete, its performance and shutdown mode feature make it a viable choice for legacy designs or specific industrial applications.
