MB88345

s DESCRIPTION

The MB88345 incorporates twenty-four 8-bit D/A converter modules.

It also contains an output amplifier, allowing driving at large current.

Since the inputs data in serial mode, it requires only three control lines for data input and can be cascaded.

The MB88345 is suitable for applications such as electronic volume controls and replacement of semi-fixed

resistors in tuning systems.

s FEATURES

• Ultra-low power consumption (1.1 mW/ch : typical)

• Compact space-saving package (QFP-32)

• Contains 24-channel R-2R type 8-bit D/A converter

• On-chip analog output amps (sink current max. 1.0 mA, source current max. 1.0 mA)

• Analog output range : 0 V to VCC

• Two separate power supply/ground lines for MCU interface block/operational amplifier output buffer block and

D/A converter block

• Serial data input : maximum operating speed 2.5 MHz

• CMOS process

s PACKAGE

32-pin Plastic QFP
