com FUJITSU SEMICONDUCTOR DATA SHEET DS04-13213-1E Linear IC Converter CMOS D/A Converter for Digital Tuning (Compatible with I2C Bus) MB88141A s DESCRIPTION The FUJITSU MB88141A is an 8-bit D/A converter with 12 built−in channels.
The 12 analog output channels have built-in OP Amps, providing large current drive capability.
Data input is compatible with I2C specifications, and is controlled by two control lines.
The built-in I/O expander function allows the MB88141A to be controlled by devices incompatible with I2C bus specifications (provides conversion between I2C serial and 8- or 4-bit parallel I/O).
The MB88141A is ideal for replacing electronic knob or pre-set variable resistance tuning devices.
