Wowza!! Eight new low-power, dual-channel, 12- and 14-bit ADCs from 65 to 250 MSPS

Today we announced eight new high-speed, ultra-low power consumption ADCs. These dual-channel devices are available in 12- and 14-bit resolutions at speeds from 65 to 250 MSPS. EVMs and samples are available for most of the devices today! Here’s the press release with links to more information…

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

DALLAS (July 21, 2011) – Texas Instruments Incorporated (TI) (NYSE: TXN) today expanded its line of high-speed, ultra-low power consumption analog-to-digital converters (ADCs) with eight dual-channel devices available in 12- and 14-bit resolutions at speeds from 65 to 250 MSPS. With these additions, the ADS42xx family provides the performance and bandwidth needed for 3G/LTE wireless base stations, portable test and measurement and software defined radio applications, while providing best-in-class power consumption. For more information and to order samples, visit www.ti.com/ads42xx-pr.

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.
