TI Introduces 14-bit, 190MSPS Analog-to-Digital Converter with Unprecedented Speed, Performance, Power, Size and Output Interface

Nov 28, 2005

DALLAS (November 28, 2005) - Utilizing its high-performance analog design expertise, Texas Instruments Incorporated (TI) (NYSE: TXN) today announced a 14-bit, 190MSPS (mega samples per second) analog-to-digital converter (ADC) with outstanding dynamic performance and low total power dissipation. The ADS5546 offers 73.2dBFS signal-to-noise ratio (SNR) and 84dBc spurious-free dynamic range (SFDR) at the maximum sample rate of 190MSPS with an input frequency of 70MHz, making it ideal for wireless communications, video and imaging, test and measurement, and instrumentation applications.

"The ADS5546 features best-in-class dynamic performance, only 1.1W total power dissipation and small 7mm x 7mm QFN packaging, which allows our customers to deliver new capabilities and features in their advanced applications," said Kent Novak, general manager for TI's high-speed products.

The ADS5546 complements TI's family of high-performance ADCs to provide designers with a range of resolutions, speed and performance options tailored to their application requirements. Each device offers superior dynamic performance and high IF capability.

  • ADS5546 - 14-bit, 190MSPS ADC with 73.2dBFS SNR and 84dBc SFDR at 70MHz IF 
  • ADS5545 - 14-bit, 170MSPS ADC with 73.5dBFS SNR and 85dBc SFDR at 70MHz IF
  • ADS5444 - 13-bit, 250MSPS ADC with 68.6dBFS SNR and 78dBc SFDR at 230MHz IF
  • ADS5440 - 13-bit, 210MSPS ADC with 69.1dBFS SNR and 79dBc SFDR at 230MHz IF



offers unprecedented interface flexibility with user-selectable CMOS or DDR LVDS outputs. The device includes an internal sample and hold, low-jitter clock buffer and internal or external reference capability. The device provides a unique set of value added features, such as programmable power scaling and user-selectable output timing and level controls. It operates from a single 3.3V supply and is specified over the industrial temperature range of -40C to +85C.

TI provides customers a state-of-the-art signal chain for wideband applications with high-speed amplifiers (




), high-speed digital-to-analog converters (


), digital up/down converters (


), crest factor reduction processors (


), quadrature modulators (




) and PLLs (


, TRF3761). The


is also optimized to work with TI's high-performance DSP platforms.

Availability and Packaging

The ADS5546 is sampling now, with volume production scheduled for 2Q 2006. The device comes in a 48-pin QFN package (7mm x 7mm) and is priced at $72.50 in 1,000 piece quantities (suggested resale pricing). Evaluation modules (EVMs) are also 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.
