MAXIM MAX19507 Technical data

General 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 DC­coupled 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 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 f
CLK
= 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 V
AVDD
= 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, 48­pin 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.
