The MAX19505 dual-channel, analog-to-digital converter(ADC) provides 8-bit resoluTIon and a maximum sample rate of 65Msps.The MAX19505 analog input accepts a wide 0.4V to1.4V input common-mode voltage range, allowing DCcoupled inputs for a wide range of RF, IF, and basebandfront-end components. The MAX19505 providesexcellent dynamic performance from baseband to highinput frequencies beyond 400MHz, making the deviceideal for zero-intermediate frequency (ZIF) and highintermediatefrequency (IF) sampling applicaTIons. Thetypical signal-to-noise raTIo (SNR) performance is49.8dBFS and typical spurious-free dynamic range(SFDR) is 69dBc at fIN = 70MHz and fCLK = 65MHz.The MAX19505 operates from a 1.8V supply.AddiTIonally, an integrated, self-sensing voltage regulatorallows operation from a 2.5V to 3.3V supply (AVDD).The digital output drivers operate on an independentsupply voltage (OVDD) over the 1.8V to 3.5V range.The analog power consumption is only 43mW per channel at VAVDD = 1.8V. In addition to low operating power, the MAX19505 consumes only 1mW in powerdown mode and 15mW in standby mode.
