TI bolsters ultra-low-power, high-speed, ADC family with eight dual-channel devices from 65 to 250 MSPS

Key features and benefits of the ADS42xx family. The 14-bit ADS4246 uses 332 mW total power at 160 MSPS, 35-percent less power than its closest competitor. The family provides options down to 92 mW per channel to reduce board heating and operating costs.

Pin-compatible 12- and 14-bit options, with speeds ranging from 65 to 250 MSPS, enable customers to move to higher resolutions and sample rates without redesigning the board.

Pin-compatible with 11-bit, 200-MSPS ADS58C28, providing a license-free export option with up to 65 MHz of high-performance RF channel bandwidth at input frequencies over 200 MHz.

6-dB programmable gain option provides the flexibility needed to achieve a high signal-to-noise ratio of up to 73.6 decibel full scale (dBFS) and spurious free dynamic range (SFDR) of up to 91 dBc for high receive sensitivity in 3G/LTE wireless infrastructure.



Tools and support

TI offers a variety of tools and support to speed development with the ADS42xx family, including:

An evaluation module (EVM) for each part.

TSW1200 digital capture tool for rapid analysis of EVMs.

An Altera-compatible high-speed mezzanine connector and Xilinx-compatible FPGA mezzanine connector, allowing ADS42xx EVMs to mate to FPGA EVMs to speed system-level prototyping.

IBIS models to verify board signal integrity requirements.

Software for calculation utilities, including an ADC harmonic calculator, anti-aliasing calculation tool, and jitter and SNR calculator.
