Product Summary

The ADS803U is a high-speed, high dynamic range, 12-bit pipelined analog-to-digital converter. This converter includes a high-bandwidth track/hold that gives excellent spurious performance up to and beyond the Nyquist rate. This high-bandwidth, linear track/hold minimizes harmonics and has low jitter, leading to excellent SNR performance. The ADS803U is also pin-compatible with the 10MHz ADS804 and the 20MHz ADS805. It provides an internal reference and can be programmed for a 2Vp-p input range for the best spurious performance and ease of driving.
