Digital temperature compensation IC
Due to the demand for compactness and lower power
dissipation, circuits for portable devices are being manufactured
as individual chips. In particular, during the manufacture of
modular devices comprised of several individual discrete devices,
significant time and effort must be devoted to adjusting the
temperature characteristic of each discrete device individually, In
addition, the demand for low power consumption is increasing.
In response to these requirements, Toshiba have developed the
TC7MTX01FX, a digital temperature compensation IC.
Toshiba have implemented this device completely in CMOS,
obviating the need to use combinations of individual electronic
components, such as thermistors and resistors, as was the case
previously. The new digital temperature compensation IC
incorporates a temperature sensor, an E²PROM and a DA
Weight: 0.02 g (typ.)
converter. The IC is accurate to within ±4ºC.
To meet the demand for compactness, the IC comes in the World’s smallest and flattest 16-pin package (US16).
