1-4. 8-bit 12-ch D/A converter (M62352GP)
1-4-1. Outline
The M62352 is a CMOS semi-conductor integrated circuit
that has 8-bit D/A converters for 12 channels as well as
high-performance buffer operational amplifiers, one each
at the output of each channel. Receiving serial input data,
the IC device can be readily used with an MCU by
coupling the 3 DI, CLK and LD lines. It is also equipped
with a Do pin for cascade connection. The built-in buffer
operational amplifiers are of the so-called full-swing type,
and work in a wide operating input/output voltage range.
These amplifiers are also much more stable against
capacitive load. The IC is best suited for regulating
electronic controls (VCA), replacing semi-fixed adjusting
resistors and other applications.
