8-bit 12ch D/A Converter with Buffer Amplifiers

R03DS0020EJ0300

Rev.3.00

Jul 25, 2013

Description

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.

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 )

· 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)

Application

· Conversion from digital data to analog control data for home-use and industrial equipment.
