DESCRIPTION
M62382FP is a semiconductor integrated circuit of 5V CMOS structure with 12-bit 4 channels of built-in multiplying D-A converters and 8-bit 8 channels of built-in multiplying D-A converters.8-bit D-A converters,when used in combination with 12-bit D-A converters,can operate in a wider range.Parallel data input under the 2 modes(A,B) of channel assignment allows for easier usage.

FEATURES
*Built-in low power 12-bit 4 channels D-A converters *8-bit D-A converter with buffer making full swing between Vcc and GND. *2 modes(A,B)of channel assignment *Zero level function Built-in function of retaining arbitrary assingned data in 12-bit D-A converter.In normal use,output voltage can be switched to the voltage corresponding to the formerly assigned data by the setting of Z01,making it possible to caribrate the data(output voltage value).

By connecting the output terminal of 8bit D-A converter with the upper reference voltage of 12bit D-A converter, D-A converter equivalent to 20bit is configurated to have higher precision configuration. If more minute output variation is needed, 8bit D-A converter can be utilized for compensation like this.

Caution : This IC has four different kinds of terminals which are to be applied by constant voltage when used. (VCC, VDD, VrefU, VrefL) D-A converter precision may be worsened when ripple voltage or spike is duplicated on these four teminals. So please be sure to put capacitor between each terminal and GND for stabilized D-A converter operation.
