Serial data transfer type input can easily be used through a combination of three lines: DI, CLK, and LD.
Very small QFN package is added to lineup. It is suitable for a small mounting and reduces the mounting area.
Description
· 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)

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.
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.
