TI Expands ADC Family with Eight Dual-channel Devices

Texas Instruments Inc. (TI) has 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 65MSPS to 250MSPS. 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.

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

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

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

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