Description
The R2A20152 is an integrated circuit semiconductor of CMOS structure with 2 channels of built in D/A
converters with output buffer operational amplifiers. It is the characteristic improvement version of M62332.
The input interface is I²C Bus serial data method, and connects with a microcomputer with minimum wiring.
It conforms FAST-MODE of I²C BUS Specifications.
The output circuit is composed of buffer operational amplifier with sync and source drive capacity of 1.0 mA
or more, and it operates in the whole voltage range from VCC to ground.
Features
• Guarantee Differential nonlinearity error : +/-0.7LSB, Nonlinearity error : +/-1.0LSB
• Digital data transfer format: I²C BUS serial data method (Corresponds to Fast mode: 400kHz)
• Output buffer operational amplifier: It operates in the whole voltage range from VCC to ground.
• High output current drive capacity: +/-1.0 mA over
• Very small size SON-8 package
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, LCD-monitor, or etc.
Blurring correction control or various control of the interchangeable lens of digital camera.
