MB88141A Datasheet | Fujitsu Semiconductor Limited

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 patible 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 inpatible 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. s FEATURES - - - - - Ultra-low power consumption (0.9 m W/channel Typ.)
