The MAX19505 is a dual-channel 8-bit ADC with a maximum sample rate of 65Msps. It operates from a 1.8V supply and supports ZIF and IF sampling.
The MAX19505 dual‑channel analog‑to‑digital converter provides 8‑bit resolution with a maximum sample rate of 65 Msps. It operates from a 1.8 V supply (or 2.5 V‑3.3 V via an internal regulator) and consumes only 43 mW per channel at 65 Msps. The device features a wide 0.4 V‑1.4 V common‑mode input range and delivers 49.8 dBFS SNR and 69 dB SFDR at 70 MHz.
The ADC is offered in a compact 7 mm × 7 mm 48‑pin thin QFN package and is rated for –40 °C to +85 °C operation. It includes programmable registers accessed via a 3‑wire SPI interface, selectable dual or multiplexed CMOS data buses, and various power‑management modes (active, standby, power‑down).
