The MAX19506 dual-channel, analog-to-digital converter(ADC) provides 8-bit resolution and a maximum samplerate of 100Msps.The MAX19506 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 MAX19506 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 = 100MHz.
The MAX19506 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 57mW per channel at VAVDD = 1.8V. In addition to low operating power, the MAX19506 consumes only 1mW in powerdown mode and 17mW in standby mode.
