The TC72 and TC77 are CMOS silicon temperature sensors that provide an accurate digital temperature measurement to solve thermal measurement problems.Data is converted from an internal diode temperaturesensing element to a digital format that can be directly interfaced to a microcontroller, as shown in Figure 1. The TC72 and TC77 sensors offer many system-level advantages, including the integration of the sensor and signal conditioning circuitry in a small Integrated Circuit (IC) package.
