This datasheet provides details on the 12-Bit, 170/210 MSPS 3.3 V A/D Converter AD9430
The AD9430 is a 12‑bit, monolithic sampling ADC optimized for high performance, low power, and ease of use. It operates up to 210 MSPS, supports both LVDS and demultiplexed CMOS outputs, and includes on‑chip reference and track‑and‑hold circuitry. The device requires a single 3.3 V supply and provides flexible data formats (two's complement or offset binary).
The datasheet details electrical specifications, timing diagrams, absolute maximum ratings, and ordering information. Typical performance includes 65 dB SNR, 10.6‑bit ENOB at 70 MHz, and 1.3 W power dissipation at 210 MSPS. The part is supplied in a 100‑lead thin‑quad flat package and is rated for industrial temperature range (‑40 °C to +85 °C).
