The ADS807 is a high-speed, high dynamic range, 12-bit pipelined analog-to-digital converter. This converter includes a high-bandwidth track-and-hold that gives excellent spurious performance up to and beyond the Nyquist rate. The differential nature of this trackand-hold and A/D circuitry minimizes even-order harmonics and gives excellent common-mode noise immunity. The track-and-hold can also be operated singleended. The ADS807 provides for setting the full-scale range of the converter without any external reference circuitry. The internal reference can be disabled allowing low drive, internal references to be used for improved tracking in multichannel systems.
