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 V^CC[V]

• Two analog output reference voltage : Analog data can be output in different reference voltages.

This device contains circuitry to protect the inputs against damage due to high static voltages or electric fields. However, it is advised that normal precautions

be taken to avoid application of any voltage higher than maximum rated voltages to this high impedance circuit.
