Maxim MAX1421 12‑Bit 40 Msps 3.3 V Low‑Power ADC with Internal Reference Datasheet
The MAX1421 is a 12‑bit, 40 Msps analog‑to‑digital converter optimized for low‑power, high‑dynamic‑range applications such as imaging and digital communications. It operates from a single 3.3 V supply, consumes only 188 mW, and provides a fully‑differential input path with a 400 MHz small‑signal bandwidth.
The datasheet lists electrical characteristics, absolute maximum ratings, timing parameters, and typical operating curves. It also includes ordering information, a 48‑pin TQFP package outline, pin configuration, and power‑down modes (reference shutdown and full shutdown).
