M62382FP

5V TYPE 12-BIT 4CH COMPOSITE MULTIPLYING D-A CONVERTER

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.

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

1 2 24 25

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.
