ADS5277 Overview
Key Features
- The word output of each internal ADC is serialized and transmitted either MSB or LSB first
- The word consists of 12 bits, of which the 2 LSBs are zeroes and the remaining 10 bits correspond to the output from the ADC
- This formatting is done in order to keep the interface compatible with the 12-bit parts of the family
- In addition to the eight data outputs, a bit clock and a word clock are also transmitted
- The bit clock is at 6x the speed of the sampling clock, whereas the word clock is at the same speed of the sampling clock
- The ADS5277 provides internal references, or can optionally be driven with external references
- Best performance is achieved through the internal reference mode
- The ADS5277 is available in a PowerPAD TQFP-80 package and is specified over a –40°C to +85°C operating range
