The MAX19507 dual-channel, analog-to-digital converter(ADC) provides 8-bit resoluTIon and a maximum sample rate of 130Msps.The MAX19507 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 baseband front-end components. The MAX19507 provides excellent dynamic performance from baseband to high input frequencies beyond 400MHz, making the deviceideal for zero-intermediate frequency (ZIF) and highintermediate frequency (IF) sampling applicaTIons. The typical signal-to-noise raTIo (SNR) performance is 49.8dBFS and typical spurious-free dynamic range (SFDR) is 69dBc at fIN = 70MHz and fCLK = 130MHz.The MAX19507 operates from a 1.8V supply. AddiTIonally, an integrated, self-sensing voltage regulator allows operation from a 2.5V to 3.3V supply (AVDD).The digital output drivers operate on an independent supply voltage (OVDD) over the 1.8V to 3.5V range.The analog power consumption is only 74mW per channel at VAVDD = 1.8V. In addition to low operating power, the MAX19507 consumes only 1mW in powerdown mode and 21mW in standby mode.
