8-bit 8-ch multiplying d-a
converter with buffer
amplifiers
general description
the utc m62364 is a cmos 8-bit, 8-ch d/a
converter having a multiplying function and output
buffer amplifiers. it has a serial data input and can
easily communicate with a microcontroller by the
simple three-wiring method (di,clk,ld).
the output buffer amplifiers operating in ab-class has
both sinking and driving capabilities of 1.0ma or more
and can operate in a whole supply range from vdd to
gnd.
the ic is suitable for a use in automatic adjustment
applications in conjunction with a mcu by utilizing the
terminal do for a cascading connection.
features

r-2r with higher-order segment method
*8 buffer amplifiers operating in a whole supply
voltage range from vdd to gnd
*4-quadrant multiplication
application
digital to analog conversion for consumer and
industrial equipment. gain setting and automatic
adjustment of display-monitor and ctv.
