FEATURES

APPLICATIONS

•

Ultralow Power with Single 1.8V Supply,

CMOS Output:

•

Wireless Communications Infrastructure

Software Defined Radio

Power Amplifier Linearization

–

183mW total power at 65MSPS

277mW total power at 125MSPS

332mW total power at 160MSPS

DESCRIPTION

•

High Dynamic Performance:

The ADS424x/422x are low-speed variants of the

ADS42xx ultralow-power family of dual-channel,

14-bit/12-bit analog-to-digital converters (ADCs).

Innovative design techniques are used to achieve

–

88dBc SFDR at 170MHz

71.4dBFS SNR at 170MHz

•

Crosstalk: > 90dB at 185MHz

Programmable Gain up to 6dB for

SNR/SFDR Trade-off

DC Offset Correction

Output Interface Options:

high-dynamic

performance,

while

consuming

extremely low power with 1.8V supply. This topology

makes the ADS424x/422x well-suited for multi-carrier,

wide-bandwidth communications applications.

•

The ADS424x/422x have gain options that can be

used to improve SFDR performance at lower

full-scale input ranges. These devices include a dc

offset correction loop that can be used to cancel the

ADC offset. Both DDR (double data rate) LVDS and

parallel CMOS digital output interfaces are available

in a compact QFN-64 PowerPAD™ package.

–

1.8V parallel CMOS interface

Double data rate (DDR) LVDS with

programmable swing:

–

Standard swing: 350mV

Low swing: 200mV

•

Supports Low Input Clock Amplitude

Down to 200mV_PP

Package: QFN-64 (9mm × 9mm)

The devices include internal references while the

traditional reference pins and associated decoupling

capacitors have been eliminated. All devices are

specified over the industrial temperature range

(–40°C to +85°C).
