Hi Alex,
Just so that I'm clear, are you looking for a 12-16bit ADC with integrated EEPROM, is that correct? And are you looking for I2C communication? How will the EEPROM be used (FIFO, other data storage)?
Have you considered a microcontroller with integrated FLASH and integrated ADCs?
Best regards,
Bob B
hi Bob
yes, I am looking for a 12-16bit ADC with integrated EEPROM with I2C comm
I need a solution ,spec as below
ADC+EEPROM,2-channel
EEPROM 1Kbyte
ADC 12bit~16bit.
power: 5.5V (TYP)or 5.5V
Have you considered a microcontroller with integrated FLASH and integrated ADCs?-->no ,we already have the MCU solution, need a extra ADC WITH ROM
Thank
Hi Alex,
You have not explained the usage for the EEPROM. We have some devices with FIFO, but I know of no such device within the portfolio using I2C communication with that much data storage capacity. There may be some possible alternatives if I knew the sensor type, speed of data required and the reason behind the EEPROM storage requirement.
Best regards,

Hello Bob,
May I know which ADCs have data storage capacity? One of my customer is looking for this kind of ADC. The product is wireless faul inductor which is put on power line. The customer want to set up an interrupt. When the interrupt comes, the data read from sensors can be sent for end user.

Hi Wenting,
Most of the precision ADC portfolio is based on higher speed products using an SPI interface. Such devices include TLV2544 family, the TLC2574 family and the ADS8201. You could also look into the ADS7142 which is an I2C interface. Another possible device would be the ADS7924. The ADS7142 and ADS7924 are interesting devices in that they can do the monitoring for you and send the interrupt to the micro if a threshold is exceeded. The downside of the ADS7924 is that the data is only buffered once.
This is not an exhaustive list, but would seem to be the devices most practical.
Best regards,
Bob B
