Active: In Production.
Description
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 to 1.4V input common-mode voltage range, allowing DC-coupled 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 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 = 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.
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 inputs 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 MAX19507 is available in a small 7mm x 7mm, 48-pin thin QFN package and is specified over the -40°C to +85°C 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 MAX19505 and MAX19506 data sheets for pin- and feature-compatible 8-bit, 65Msps and 100Msps versions, respectively.
