ADS41B49: 14-Bit, 250MSPS  
ADS41B29: 12-Bit, 250MSPS  
The ADS41B29/B49 are members of the  
ultralow-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

Integrated High-Impedance  
Analog Input Buffer:

Input Capacitance: 2pF  
200MHz Input Resistance: 3kΩ  
•

Maximum Sample Rate: 250MSPS  
Ultralow Power:  
multi-carrier,  
wide

communications

1.8V Analog Power: 180mW  
3.3V Buffer Power: 96mW  
applications such as PA linearization.  
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)
