MB88346L Datasheet D/A Converter for Digital Tuning

Manufacturer: Fujitsu Semiconductor Limited

Overview: FUJITSU SEMICONDUCTOR DATA SHEET DS04-13511-2E Linear IC Converter CMOS D/A Converter for Digital Tuning (12-channel, 8-bit, on-chip OP amp, low-voltage) MB88346L s DESCRIPITON The Fujitsu MB88346L is an 8-bit D/A converter capable of low-voltage operation, and designed with a built-in amp on each of its 12 analog output lines for large-current drive capability. The use of serial data input means that only three control lines are required, and enables cascade connection of multiple MB88346L chips. The MB88346L is suitable for applications such as electronic volume controls and replacement of semi-fixed resistors in tuning systems. In addition, the MB88346L is both function-compatible and pin-compatible with the MB88346B now in use, allowing easy substitution of the MB88346L for reduced supply voltage.
