8-bit 6ch D/A Converter with Buffer Amplifiers

R03DS0018EJ0100

Rev.1.00

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.
