描述


The ADS5271 is a high-performance, 50MSPS, 8-channel analog-to-digital converter (ADC). Internal referencesare provided, simplifying system design requirements. Low power consumption allows for the highest of system integration densities. Serial LVDS (low-voltage differential signaling) outputs reduce the number of interface lines and package size.

An integrated phase lock loop (PLL) multiplies the incoming ADC sampling clock by a factor of 12. This high-frequency LVDS clock is used in the data serialization and transmission process. The word output of each internal ADC is serialized and transmitted either MSB or LSB first. 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 ADS5271 provides internal references, or can optionally be driven with external references. Best performance is achieved through the internal reference mode.

The device is available in a TQFP-80 PowerPAD package and is specified over a -40°C to +85°C operating range.
