DESCRIPTION
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 ponents. A lower input voltage of 1.5Vp-p or 1Vp-p can...
