MB88345 - D/A Converter for Digital Tuning

General 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.

Key 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.
