MB88346L
DESCRIPTION
Fujitsu Microelectronics MB88346L 12-channel 8-bit converter capable low-voltage operation that amplifiers built into each analog output lines deliver heavy-current drive capability. serial data input means that only three control lines required, enables cascade connection multiple MB88346L chips. MB88346L suitable applications such electronic volume controls replacing trimmer potentiometers tuning systems. addition, MB88346L both function-compatible pin-compatible currently used MB88346B, making easy reduce voltage level system simply replacing MB88346B with MB88346L.
FEATURES
