FUJITSU SEMICONDUCTOR DATA SHEET DS04-13505-3E LINEAR IC 8-Bit D/A Converter with Operational Amplifier Output Buffers MB88344/88344B ■ DESCRIPTION MB88344/MB88344B are 8-bit 36 channels D/A converters which have two reference voltages to use 36 channels as 12 channels and 24 channels independently. Each output channels has an operational amplifier output buffer and so large current drive is possible. In the MB88344B, 6 Channels of DAC output (AO31-AO36) have four data registers each and so, the analog output can be changed by the address input from A0 and A1 pins. Digital data are input to the devices in serial and it is controlled by CLK and LD pins. This configuration makes a cascade connections between devices. The MB88344/MB88344B are suitable for electronic volumes and replacement for potentiometers for adjustment, in addition to normal D/A converter applications. ■ FEATURES • • • • • • Ultra low power consumption : Type. 1.1mW/channel Ultra small package Conversion method : R-2R resistor ladder On-chip operational amplifier output buffers : Max. +1.0/–1.0mA analog output sink/source current capability Analog data output range : 0 to VCC [V] Two analog output reference voltage : Analog data can be output in different reference voltages.

The information and circuit diagrams in this document presented as examples of semiconductor device applications, and are not intended to be incorporated in devices for actual use. Also, FUJITSU is unable to assume responsibility for infringement of any patent rights or other rights of third parties arising from the use of this information or circuit diagrams. FUJITSU semiconductor devices are intended for use in standard applications (computers, office automation and other office equipment, industrial, communications, and measurement equipment, personal or household devices, etc.). CAUTION: Customers considering the use of our products in special applications where failure or abnormal operation may directly affect human lives or cause physical injury or property damage, or where extremely high levels of reliability are demanded (such as aerospace systems, atomic energy controls, sea floor repeaters, vehicle operating controls, medical devices for life support, etc.) are requested to consult with FUJITSU sales representatives before such use. The company will not be responsible for damages arising from such use without prior approval. Any semiconductor devices have inherently a certain rate of failure. You must protect against injury, damage or loss from such failures by incorporating safety design measures into your facility and equipment such as redundancy, fire protection, and prevention of over-current levels and other abnormal operating conditions.
