■ 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.

■ 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
