8-bit 2ch D/A Converter with Buffer
R03DS0016EJ0100
Rev.1.00
2011.09.05
Description
The R2A20162 is an integrated circuit semiconductor of CMOS structure with 2 channels of built in D/A
converters with output buffer op-amps. It is the electrical characteristic improvement version of the M62342.
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 SON package is added to lineup. It is suitable for a small mounting and reduces the mounting area.
Features
Guarantee Differential Nonlinearity error : +/- 0.7LSB, Nonlinearity error : +/- 1.0LSB,
Data transfer format: 10-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 mall size package line-up: SON-8 (pin pitch: 0.5mm), TSSOP-8 (pin pitch 0.65mm)
Application
Conversion from digital data to analog control data for home-use and industrial equipment.
Signal gain control or automatic adjustment of LCD-TV, PDP-TV or LCD display-monitor.
Blurring correction control or various control of the interchangeable lens of digital camera for self
adjustment by combination with microcomputer and EEPROM. (substitution of half fixed resistance)

Precaution For use
Supply voltage terminal (Vcc) is also used for D/A converter upper reference voltage setting. If ripple or
spike is input this terminal, accuracy of D/A converter is down, So, when use this device, please connect
capacitor among Vcc to 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 ( 0.1 µF Max ) among output to GND for every noise elimination.

7. Renesas Electronics products are classified according to the following three quality grades: "Standard", "High Quality", and "Specific". The recommended applications for each Renesas Electronics product
depends on the product's quality grade, as indicated below. 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 categorized as "Specific" without the prior written consent of Renesas Electronics. Further, you may not use any Renesas Electronics product for any application for
which it is not intended without the prior written consent of Renesas Electronics. 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 an application categorized as "Specific" or for which the product is not intended where you have failed to obtain the prior written consent of Renesas Electronics.
The quality grade of each Renesas Electronics product is "Standard" unless otherwise expressly specified in a Renesas Electronics data sheets or data books, etc.
"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.
"High Quality": Transportation equipment (automobiles, trains, ships, etc.); traffic control systems; anti-disaster systems; anti-crime systems; safety equipment; and medical equipment not specifically
designed for life support.
"Specific":
Aircraft; aerospace equipment; submersible repeaters; nuclear reactor control systems; medical equipment or systems for life support (e.g. artificial life support devices or systems), surgical
implantations, or healthcare intervention (e.g. excision, etc.), and any other applications or purposes that pose a direct threat to human life.
8. You should use the Renesas Electronics products described in this document within the range specified by Renesas Electronics, especially with respect to the maximum rating, operating supply voltage
range, movement power voltage range, heat radiation characteristics, installation and other product characteristics. Renesas Electronics shall have no liability for malfunctions or damages arising out of the
use of Renesas Electronics products beyond such specified ranges.
9. Although Renesas Electronics endeavors to improve the quality and reliability of its products, semiconductor products have specific characteristics such as the occurrence of failure at a certain rate and
malfunctions under certain use conditions. Further, Renesas Electronics products are not subject to radiation resistance design. Please be sure to implement safety measures to guard them against the
possibility of physical injury, and injury or damage caused by fire in the event of the failure of a Renesas Electronics product, such as safety design for hardware and software including but not limited to
redundancy, fire control and malfunction prevention, appropriate treatment for aging degradation or any other appropriate measures. Because the evaluation of microcomputer software alone is very difficult,
please evaluate the safety of the final products or system manufactured by you.
10. Please contact a Renesas Electronics sales office for details as to environmental matters such as the environmental compatibility of each Renesas Electronics product. Please use Renesas Electronics
products in compliance with all applicable laws and regulations that regulate the inclusion or use of controlled substances, including without limitation, the EU RoHS Directive. Renesas Electronics assumes
