Texas Instruments Inc. introduced the industry’s fastest 4-channel, 14-bit A/D converter, clocking in at 250 MSPS.
The high-density ADS4449 enables receiver systems to support up to 125 MHz of instantaneous bandwidth in extremely small forms, such as multiple input and multiple output (MIMO) base stations and munitions guidance, or in greater density applications, such as active electrically scanned array (AESA) and other phased-array radars.
According to TI, the ADS4449 is the highest-performance 4-channel A/D converter at 250 MSPS, providing an additional 4-dB SNR and 8-dB SFDR, compared to existing 4-channel A/D converters. By packing four 14-bit, 250-MSPS ADCs into a single package, the ADS4449 enables system designers to maintain small form factors and increase dynamic performance and signal bandwidth, while reducing power consumption and cost.
