The ADS803 is a 12-bit, 5MHz sampling analog-to-digital converter with high SFDR, high SNR, low power, low DLE and flexible input range. It is suitable for IF and baseband digitization, CCD imaging scanners and test instrumentation.
The ADS803 is a high‑speed, 12‑bit pipelined analog‑to‑digital converter offering 5 MHz sampling, 82 dB SFDR at Nyquist and 69 dB SNR. It features low power consumption (115 mW typical) and selectable input ranges of 2 Vp‑p or 5 Vp‑p, with an over‑range indicator flag.
The device is supplied in an SSOP‑28 package and includes an internal reference, flexible input‑range selection, and detailed pin configurations. Typical applications include IF and baseband digitization, CCD imaging scanners, and test instrumentation.
