Description
The M62368GP is a CMOS semiconductor IC, containing 6 channels of 8-bit D/A converters. It is operable with a low
supply voltage between 2.7 to 3.6 V, and is easy to use due to serial data input, and 3-pin (DI, CLK, LD) connection
with microcomputer.
The IC also contains D
O
pin terminal, enabling cascade connection, and therefore is suitable for automatic control in
combination with a microcomputer.
