SBAS486E – NOVEMBER 2009–REVISED JULY 2012

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

with Analog Buffers

Check for Samples: ADS41B29, ADS41B49

FEATURES

DESCRIPTION

The ADS41B29/B49 are members of the ultralow-

•

ADS41B49: 14-Bit, 250MSPS

ADS41B29: 12-Bit, 250MSPS

power ADS4xxx analog-to-digital converter (ADC)

family, featuring integrated analog input buffers.

These devices use innovative design techniques to

achieve high dynamic performance, while consuming

extremely low power. The analog input pins have

buffers, with benefits of constant performance and

input impedance across a wide frequency range. The

devices are well-suited for multi-carrier, wide

bandwidth communications applications such as PA

linearization.

•

Integrated High-Impedance

Analog Input Buffer:

–

Input Capacitance: 2pF

200MHz Input Resistance: 3kΩ

•

Maximum Sample Rate: 250MSPS

Ultralow Power:

–

1.8V Analog Power: 180mW

3.3V Buffer Power: 96mW

The ADS41B49/29 have features such as digital gain

and offset correction. The gain option can be used to

improve SFDR performance at lower full-scale input

ranges, especially at high input frequencies. The

integrated dc offset correction loop can be used to

estimate and cancel the ADC offset. At lower

sampling rates, the ADC automatically operates at

scaled-down power with no loss in performance.

I/O Power: 135mW (DDR LVDS)

•

High Dynamic Performance:

–

SNR: 69dBFS at 170MHz

SFDR: 82.5dBc at 170MHz

Output Interface:

–

Double Data Rate (DDR) LVDS with

Programmable Swing and Strength:

The devices support both double data rate (DDR)

low-voltage differential signaling (LVDS) and parallel

CMOS digital output interfaces. The low data rate of

the DDR LVDS interface (maximum 500MBPS)

makes it possible to use low-cost field-programmable

gate array (FPGA)-based receivers. The devices

have a low-swing LVDS mode that can be used to

further reduce the power consumption. The strength

of the LVDS output buffers can also be increased to

support 50Ω differential termination.

–

Standard Swing: 350mV

Low Swing: 200mV

Default Strength: 100Ω Termination

2x Strength: 50Ω Termination

–

1.8V Parallel CMOS Interface Also

Supported

•

Programmable Gain for SNR/SFDR Trade-Off

DC Offset Correction

The devices are available in a compact QFN-48

package and are specified over the industrial

temperature range (–40°C to +85°C).

Supports Low Input Clock Amplitude

Package: QFN-48 (7mm × 7mm)
