TI Unveils 12-bit, 500 MSPS Analog-to-Digital Converter (ADC)

Texas Instruments Incorporated (TI) (NYSE: TXN) introduced a monolithic 12-bit, 500 MSPS (mega samples per second) 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 and provides increased benefits to the system such as the following:

  • Improved power amplifier linearization for digital pre-distortion (DPD) solutions
  • Enhanced resolution for radar and advanced imaging
  • Implementation of more standards in software-defined radios
  • Direct IF sampling or elimination of an IF stage in multi-carrier receivers
  • Advanced system performance for test and measurement

TI provides customers a state-of-the-art signal chain to complement the ADS5463 including high-speed amplifiers (THS4304, THS4509, THS4511, THS9000/9001), high-speed digital-to-analog converters (DAC5687) and a clock synchronizer and jitter cleaner (CDCM7005). The ADS5463 is also optimized to work with TI’s TMS320(TM) high-performance DSP platforms.

Availability and Packaging
The ADS5463 is now available in an 80-pin TQFP PowerPAD(TM) 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. Samples and evaluation modules (EVMs) are available.

TI offers analog engineers a wide-ranging support infrastructure that includes training and seminars, design tools and utilities, technical documentation, evaluation modules, an online KnowledgeBase, a product information hotline and a comprehensive offering of samples that ship within 24 hours of request.
