General Description

The MAX19517 dual-channel, analog-to-digital converter

(ADC) provides 10-bit resolution and a maximum sam-

ple rate of 130Msps.

The MAX19517 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 MAX19517 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

59.8dBFS and typical spurious-free dynamic range

(SFDR) is 82dBc at f

= 70MHz and f

CLK

= 130MHz.

The MAX19517 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 74mW per chan-

nel at V

AVDD

= 1.8V. In addition to low operating

power, the MAX19517 consumes only 1mW in power-

down mode and 21mW in standby mode.

Various adjustments and feature selections are avail-

able 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 out-

put data bus that can also be configured as a single

multiplexed parallel CMOS bus.

The MAX19517 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 MAX19505, MAX19506, and MAX19507

data sheets for pin- and feature-compatible 8-bit,

65Msps, 100Msps, and 130Msps versions, respectively.

Refer to the MAX19515 and MAX19516 data sheets for

pin- and feature-compatible 10-bit, 65Msps and

100Msps versions, respectively.
