LINEAR
8-Bit Converter
with Operational Amplifier Output Buffers
MB88344/88344B
DESCRIPTION
MB88344/MB88344B 8-bit channels converters which have reference voltages channels channels channels independently. Each output channels operational amplifier output buffer large current drive possible. MB88344B, Channels output (AO31-AO36) have four data registers each analog output changed address input from pins. Digital data input devices serial controlled pins. This configuration makes cascade connections between devices. MB88344/MB88344B suitable electronic volumes replacement potentiometers adjustment, addition normal converter applications.
FEATURES
Ultra 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 analog output reference voltage Analog data output different reference voltages.
