Description
The R2A20162 is an integrated circuit semiconductor of CMOS structure with 2 channels of built in D/A converters with output buffer op-amps. It is the electrical characteristic improvement version of the M62342. Serial data transfer type input can easily be used through a bination 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 ponent parts. Very small SON package is added to lineup. It is suitable for a small mounting and reduces the mounting area.
Features
- Guarantee Differential Nonlinearity error : +/- 0.7LSB, Nonlinearity error : +/- 1.0LSB,
- Data transfer format: 10-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 mall size package line-up: SON-8 (pin pitch: 0.5mm), TSSOP-8 (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 camera for self adjustment by bination with microputer and EEPROM. (substitution of half fixed resistance)
