The ADS808 is a high-dynamic range, 12-bit, 70MHz, pipelined Analog-to-Digital Converter (ADC). It includes a high-bandwidth linear track-and-hold that has a low jitter of only 0.25ps rms, leading to excellent SNR performance. The clock input can accept a low-level differenTIal sine wave or square wave signal down to 0.5Vp-p, further improving the SNR performance. It also accepts a single-ended clock signal and has flexible threshold levels.
The ADS808 has a 2Vp-p differenTIal input range (1Vp-p • 2 inputs) for opTImum signal-to-noise raTIo. The differential operation gives the lowest even-order harmonic components. A lower input voltage of 1.5Vp-p or 1Vp-p can also be selected using the internal references, further optimizing SFDR.
