SBAS483D – NOVEMBER 2009–REVISED APRIL 2010

14-/12-Bit, 160/250MSPS, Ultralow-Power ADC

Check for Samples: ADS4126, ADS4129, ADS4146, ADS4149

FEATURES

•

DC Offset Correction

•

Maximum Sample Rate: 250MSPS

Supports Low Input Clock Amplitude Down To

200mV_PP

•

Ultralow Power with 1.8V Single Supply:

•

Package: QFN-48 (7mm × 7mm)

–

200mW Total Power at 160MSPS

265mW Total Power at 250MSPS

DESCRIPTION

•

High Dynamic Performance:

The ADS414x/2x are

a family of 14-bit/12-bit

–

SNR: 70.6dBFS at 170MHz

SFDR: 84dBc at 170MHz

analog-to-digital converters (ADCs) with sampling

rates up to 250MSPS. These devices use innovative

design techniques to achieve high dynamic

performance, while consuming extremely low power

at 1.8V supply. The devices are well-suited for

multi-carrier,

applications.

•

Dynamic Power Scaling with Sample Rate

Output Interface

–

Double Data Rate (DDR) LVDS with

Programmable Swing and Strength

wide

bandwidth

communications

–

Standard Swing: 350mV

The ADS414x/2x have fine gain options that can be

used to improve SFDR performance at lower

full-scale input ranges, especially at high input

frequencies. They include a dc offset correction loop

that can be used to cancel the ADC offset. At lower

sampling rates, the ADC automatically operates at

scaled down power with no loss in performance.

Low Swing: 200mV

Default Strength: 100Ω Termination

2x Strength: 50Ω Termination

–

1.8V Parallel CMOS Interface Also

Supported

•

Programmable Gain up to 6dB for SNR/SFDR

Trade-Off

The ADS414x/2x are available in a compact QFN-48

pacakge and are specified over the industrial

temperature range (–40°C to +85°C).
