Texas Instruments has introduced a monolithic 12-bit, 500 MSPS analog-to-digital converter (ADC) providing unmatched size and performance. The new pipeline ADC offers 64.5 dBFS signal-to-noise ratio (SNR) up to 500 MHz input frequency at 500 MSPS, bringing a new class of performance to customers previously confined to 8- and 10-bits of resolution. In a space-saving 14 mm x 14 mm package, the new ADC meets the resolution and speed requirements of applications such as communications, amplifier linearization, test and measurement instrumentation, software-defined radio and radar and imaging systems.

Manufactured in TI's proprietary BiCom3 process technology optimized for high speed and low noise, the ADS5463 provides 84 dBc SFDR, 10.5 ENOB and an input bandwidth of 2 GHz while only consuming 2.25 watts of power. The ADC includes an internal reference generator and LVDS outputs
with a half-clock rate, data-ready signal to simplify designs. In addition, the ADS5463 is a pin-compatible family member to TI's 13-bit, 250/210 MSPS ADS5444/ADS5440.

The ADS5463 is now available in an 80-pin TQFP PowerPADT package (14 mm x 14mm) and is priced at $125.00 in 1,000-piece quantities for industrial temperature. Military temperature range, enhanced plastic and space-qualified versions are also available from TI.
