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 V AVDD = 1.8V. In addition to low operating power, the MAX19505 consumes only 1mW in powerdown mode and 15mW in standby mode. Various adjustments and feature selections are available through programmable registers that are accessed through the 3-wire serial-port interface. Alternatively, the serial-port interface can be disabled, with the three pins available to select output mode, data format, and clock-divider mode. Data outputs are available through a dual parallel CMOS-compatible output data bus that can also be configured as a single multiplexed parallel CMOS bus. The MAX19505 is available in a small 7mm x 7mm 48-pin thin QFN package and is specified over the -40C to +85C extended temperature range. Refer to the MAX19515, MAX19516, and MAX19517 data sheets for pin- and feature-compatible 10-bit, 65Msps, 100Msps, and 130Msps versions, respectively. Refer to the MAX19506 and MAX19507 data sheets for pin- and feature-compatible 8-bit, 100Msps and 130Msps versions, respectively.
