PK70 + NBPKBM-100CR: the DAC chip replacement ?

[res]

Hi guys,

I'm using the PK70 with Multi IO blade board. A simple regulator, that reads analog values, do some computations and drive a few digital inputs and a analog output.

The question is: what IC is that DAC on the NBPKBM-100CR ? I need to replace one, but I failed to find it anywhere. Its denoted as DAC8751 in the schematics and D871 77Z0 on the packaging. Can you please point me to that part somewhere online?

The story is that I have recently experienced a failure of the DAC: the analog output got stuck on ground, the system drastically slowed down. The taskscan utility has shown that the threads talking to either DAC or GPIO (on the blade board) spend a lot of time in I2C library calls. I've disconnected the chips from IIC bus and it has shown that one of the DAC were faulty.

Thanks in advance, have a good time!

On the multiblade board I have the DACs as:

Vendor:TI / Digikey
Partnumber: DAC8571IDGKR / 296-14307-1-ND
Description: IC DAC 16BIT I2C V-OUT LP 8-MSOP

So basically its a TI DAC8571IDGKR

Or Digikey:296-14307-1-ND
