NJU9252P
2-DIGIT SINGLE CHIP A/D CONVERTER
sGENERAL DESCRIPTION
The NJU9252P is a low operating current, high
performance 2-digit single chip A/D converter containing a
sample/hold circuit, an oscillator, a 7-segment decoder, LED
display driver and a control circuit. The LED display
changes by the high-speed sampling rate of 4 times/s (typ).
The NJU9252P realizes to apply with few external
components, therefore it is most suited for digital meters,
digital thermometers and the others.
