The MAX1192 is an ultra-low-power, dual, 8-bit, 22Msps analog-to-digital converter (ADC)
The MAX1192 is an ultra‑low‑power, dual‑channel 8‑bit analog‑to‑digital converter that delivers 22 Msps sampling rate and a 440 MHz input bandwidth. It operates from a 2.7 V to 3.6 V analog supply and a separate 1.8 V to 3.6 V digital output supply, consuming only 27.3 mW in normal mode. The device features fully differential or single‑ended inputs, offset‑binary output format, and three power‑down modes for idle periods.
Typical applications include ultrasound and medical imaging, battery‑powered portable instruments, low‑power video, and wireless communication front‑ends. The datasheet provides electrical characteristics, timing specifications, layout recommendations, and example QAM receiver implementation details.
