ADC raises performance bar at 12bit resolution

Monolithic 12bit 500Msample/s analogue-to-digital convertor claims unmatched size and performance.

Texas Instruments has introduced a monolithic 12bit 500Msample/s analogue-to-digital convertor (ADC) providing unmatched size and performance.

The new pipeline ADC offers 64.5dB FS signal-to-noise ratio (SNR) up to 500MHz input frequency at 500Msample/s, bringing a new class of performance to customers previously confined to 8 and 10bit resolution.

In a space-saving 14 x 14mm package, the new ADC meets the resolution and speed requirements of applications such as communications, amplifier linearisation, test and measurement instrumentation, software-defined radio and radar and imaging systems.

Manufactured in TI's proprietary BiCom3 process technology optimised for high speed and low noise, the ADS5463 provides 84dBc SFDR, 10.5 ENOB and an input bandwidth of 2GHz while only consuming 2.25W 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 13bit, 250/210Msample/s ADS5444/ADS5440 and provides increased benefits to the system.

The ADS5463 is now available in an 80-pin TQFP PowerPAD package (14 x 14mm) and is priced at US $125.00 in 1000-piece quantities for industrial temperature.

Military temperature range, enhanced plastic and space-qualified versions are also available from TI.
