Features
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) Block Diagram 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. 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) 10-bit shift register 8 7 6 Channel decoder Vcc CLK LD DI GND Ao2Ao1 N.C. Power on reset 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.

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.
