Maxim MAX1422 12-Bit 20Msps 3.3V Low-Power ADC with Internal Reference Datasheet
The MAX1422 is a 12‑bit, 20 Msps analog‑to‑digital converter optimized for low‑power, high‑dynamic‑performance applications such as imaging and digital communications. It operates from a single 3.3 V supply, consuming only 137 mW while delivering a typical 67 dB SNR at a 5 MHz input frequency.
The device includes a fully differential input stage with a 400 MHz small‑signal bandwidth, an internal 2.048 V bandgap reference, and three‑state parallel outputs. It is available in a 48‑pin TQFP package (7 mm × 7 mm × 1.4 mm) and supports operation over commercial (0 °C to +70 °C) and extended industrial (‑40 °C to +85 °C) temperature ranges.
