Description
Digital Temperature Compensation Ic
Manufacturer
TOSHIBA Semiconductor CORPORATION
Datasheet
Digital temperature compensation IC
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.
TC7MTX01FX, a digital temperature compensation IC.
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 E
converter. The IC is accurate to within ±4ºC.

Due to the demand for compactness and lower power
In response to these requirements, Toshiba have developed the
Toshiba have implemented this device completely in CMOS,
To meet the demand for compactness, the IC comes in the World’s smallest and flattest 16-pin package (US16).
Temperature compensation precision:
±4°C (in the range ï20~70°C)

Outputs an analog voltage whose level corresponds to 1°C
increments in the above temperature range.
Control resolution: 10.98 mV (typ.)/Bit
Linearity: ±1LSB
Output response speed: 500 µs
Supply voltage operating range: 2.7~3.3 V
