Description
The M62342 and M62343 are CMOS-structure semiconductor integrated circuits incorporating two or three 8-bit D/A converter channels with output buffer op-amps.
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 and source, and can operate over the entire voltage range from almost ground to VCC (0 to 5 V), making peripheral elements unnecessary and enabling configuration of a system with few component parts.
Features
Data transfer format 10-bit serial data input type
Output buffer op-amps Operable over entire voltage range from almost ground to VCC (0 to 5 V)
High output current capacity ±1 mA or higher
Application
Signal gain setting and automatic adjustment in CTV, and display monitors, conversion from digital data to analog data in consumer and industrial products
