HWD9480 is a high-speed, high-precision, low-power 8-bit single chip analog-to-digital converter. Its area is small, its use is simple, and it has good linearity and dynamic characteristics in the entire input range when working at 250MSPS sampling frequency.
The HWD9480 is a high‑speed, high‑precision, low‑power 8‑bit ADC that operates at up to 250 MSPS with a 3.3 V supply. It features internal 1.0 V reference, TTL/CMOS output, and supports both single‑ended and differential inputs.
The device is supplied in an LQFP‑44 package and is rated for operation from –40 °C to +85 °C. Detailed pin assignments, electrical characteristics, and performance parameters are provided in the following sections. This manual is written in Chinese.
