Holtek has launched the HT66F2742, a new ATS 24-bit A/D Flash MCU. The most important feature of this microcontroller is its integrated accurate temperature sensor (ATS) to compensate errors, e.g. during the conversion of the high-resolution integrated ADC.
The temperature sensor achieves a factory accuracy of
This makes this new device suitable for use in infrared temperature measurements, such as body temperature measurements (forehead thermometers, ear thermometers, electronic thermometers, body temperature patches) and high-precision applications for measuring ambient temperature (e.g. for monitoring cold chains).
By integrating the precise temperature sensor, a 24-bit A/D converter, an OPA and a LDO, huge savings can be made in the number of external components, resulting in a smaller product size and lower production costs, as well as simplifying component procurement for the overall product.
