M62342GP
8-Bit, 2-Channel D-A Converter (Buffered)
REJ03F0074-0100Z
Rev.1.0
Sep.19.2003
Description
The M62342GP is a CMOS-structure semiconductor integrated circuit incorporating two 8-bit D-A converter channels
with output buffer op-amps.
Serial data transfer type input can easily be used through a combination of three lines: DI, CLK, and LD.
Outputs incorporate buffer op-amps that have a drive capacity of 1 mA or above for both sink and source, and can
operate over the entire voltage range from almost ground to VCC (0 to 5 V), making peripheral elements unnecessary
and enabling configuration of a system with few component parts.
This product is currently under development, and specifications and other details may be modified at a future date.

Function
Serial data input pin. Inputs serial data with a 10-bit data length.
Serial clock input pin. Input signal from DI pin is input to 10-bit shift register at rise of
shift clock.
Load pin. When Hlevel is input to LD pin, value in 10-bit shift register is loaded into
decoder and D-A output register.
8-bit resolution D-A converter output pins
(After power-on, all channels are reset and DAC data 00h is output.)
