Dual-Channel, 8-Bit, 100Msps ADC

The MAX19506 dual-channel, Analog-to-digital converter (ADC) provides 8-bit resolution and a maximum sample rate of 100Msps. The MAX19506 Analog input accepts a wide 0.4V to 1.4V input common-mode voltage range, allowing DC- coupled inputs for a wide range of RF, IF, and base- band 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 high- intermediate 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 regula- tor 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 chan- nel at VAVDD = 1.8V. In addition to low operating power, the MAX19506 consumes only 1mW in power- down mode and 17mW in standby mode. By Maxim Integrated Products
