com FUJITSU SEMICONDUCTOR DATA SHEET DS04-13211-3E General Purpose Linear IC’s General Purpose Converters CMOS D/A Converter for Digital Tuning (With Built-in OP Amp and I/O Expander) MB88141 s DESCRIPTION The FUJITSU MB88141 is a 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 MB88141 to be controlled by devices incompatible with I2C bus specifications (provides conversion between I2C serial and 8- or 4-bit parallel I/O).
Can be adapted for tuning by electronically variable or pre-fixed resistance, etc.
s FEATURES • • • • • Ultra-low power consumption (0.
9 mW/channel Typ.
) Ultra-compact package Built-in 12-channel R-2R type 8-bit D/A converter Built-in analog output amplifier (maximum sink current 1.
