Texas Instruments announced a 13-bit, 250MSPS analog-to-digital converter (ADC). The ADS5444 offers 68dB signal-to-noise ratio (SNR) and 75dB spurious-free dynamic range (SFDR) at the maximum sample rate of 250MSPS and an input frequency of 230MHz. The ADC operates from a 5V supply, while providing LVDS-compatible digital outputs from a 3.3V supply. The device is specified over the industrial temperature range of -40C to +85C.
The ADS5444 is sampling now, with volume production scheduled for 4Q 2005. The device comes in an 80-pin TQFP PowerPad™ package and is priced at $95.00 in 1,000 piece quantities (suggested resale pricing). Evaluation modules (EVMs) are also available.
