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 to
1.4V input common-mode voltage range, allowing DCcoupled inputs for a wide range of RF, IF, and baseband
front-end components. The MAX19505 provides
excellent dynamic performance from baseband to high
input frequencies beyond 400MHz, making the device
ideal 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 = 65MHz.
The MAX19505 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 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.
