Description
The R2A20166 is an integrated circuit semiconductor of CMOS structure with 6 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 )
 Very small size package line-up: QFN-16(pin pitch: 0.5mm), TSSOP-16 (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 still camera.
 Automatic adjustment by combination with microcomputer and EEPROM.
