Rev.3.00
Jul 25, 2013
Description
The R2A20169 is an integrated circuit semiconductor of CMOS structure with 12 channels of built in D/A
unnecessary and enabling configuration of a system with few component parts.
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 source, and
can operate over the entire voltage range from almost ground to Vcc ( 0 to 5V ), making peripheral elements
unnecessary and enabling configuration of a system with few component parts.
Very small QFN package is added to lineup. It is suitable for a small mounting and reduces the mounting area.
Features
· Guarantee Nonlinearity error : +/-1.0LSB, Differential nonlinearity error : +/-0.7LSB
· Data transfer format: 12-bit serial data input type by 3 wire ( DI, SCK, LD )
· Output buffer op-amps: Operable over entire voltage range from almost ground to Vcc ( 0 to 5V )
· High output current capacity: +/-1mA or Higher
· Very small size package line-up: QFN-20 (pin pitch: 0.5mm), TSSOP-20 (pin pitch 0.65mm)
Application
· Conversion from digital data to analog control data for home-use and industrial equipment.

Precaution For use
· There are three terminals (Vcc, VrefU, VrefL) that should be impressed a constant voltage. When ripple
or spike noise is input to this terminal, there is fear that the accuracy of D/A conversion becomes lower and
this IC malfunction. So, when use this IC, please connect capacitor between these terminals (Vcc, VrefU, VrefL)
and GND for stable D/A conversion.
· This IC’s output amplifier has an advantage to capacitive load, So, it’s no problem at device action when
connect capacitor ( 0.1µF Max ) among output to GND for every noise elimination.

5. Renesas Electronics products are classified according to the following two quality grades: "Standard" and "High Quality". The recommended applications for each Renesas Electronics product depends on
the product's quality grade, as indicated below.
"Standard": Computers; office equipment; communications equipment; test and measurement equipment; audio and visual equipment; home electronic appliances; machine tools; personal electronic
equipment; and industrial robots etc.
"High Quality": Transportation equipment (automobiles, trains, ships, etc.); traffic control systems; anti-disaster systems; anti-crime systems; and safety equipment etc.
Renesas Electronics products are neither intended nor authorized for use in products or systems that may pose a direct threat to human life or bodily injury (artificial life support devices or systems, surgical
implantations etc.), or may cause serious property damages (nuclear reactor control systems, military equipment etc.). You must check the quality grade of each Renesas Electronics product before using it
in a particular application. You may not use any Renesas Electronics product for any application for which it is not intended. Renesas Electronics shall not be in any way liable for any damages or losses
incurred by you or third parties arising from the use of any Renesas Electronics product for which the product is not intended by Renesas Electronics.
