- how can i determine if it can function with ATMEGA328 ARDUINO UNO.
The TLV is controlled by the I2C bus, so it's compatible with the Arduino platform.
how would i connect them together
See answer to first question.
! so now am confused , should i use both IDE?
If you need special DSP routines in the TLV, it's probably the most convenient way to use both IDEs.
then what is the use of Arduino uno. i guess to store the code in the chip EEPROM
No, the Arduino is the microcontroller, the chief of the whole system. If you store the TLV code (if needed) in the EEPROM or in the flash memory depends probably on the size of that code. A UNO has 1kB of EEPROM but 32kB of flash memory.
- what is 10 bit chip from 8 bit chip from 12 bit chip !?
That depends on the context. Usually it's the data size. If the chip is a ADC, the bits specify the converters resolution. If the chip is a processor it's the width of the data bus, so the data size the processor is able to handle in one instruction.
