IT883478-bit 8-channel D/A converter


IT88347 is a 8 Channels R2R CMOS Digital to Analog Converter (DAC) with 8-bit resolution, low leakage current and low operating current. The IT88347 has built in operational amplifier output buffers which canoperate in full-swing voltage range from GND to VCC (3.0V to 5.5V) with the Drive/Sink current up to max. 1mA.

The Digital Input data (DI) can be serially shifted and latched with a max. 2.5MHz clock (CLK). The latched 12-bit digital data is converted into analog DC voltage in the range from VSS to VDD with 8-bit resolution to one of the eight channels’ D/A converter in a max. 100μs settling time.



  • Wide Operation Power Supply range from 3.0V to 5.5V without sacrificing performance

  • High Linearity Resolution DNL < +- 0.5LSB; INL <= +-0.6LSB

  • 12 bits serial data input controlled by 3 wire serial data transfer pins DI, CLK, LD

  • Max. 2.5MHz serial digital data input

  • Serial I/O data for cascade application

  • Max. 1.0mA analog output drive/sink current for each DAC
