Analog to Digital Converters offer 210 MSPS operation.
Press Release Summary:
Specified over -40 to +85°C range, ADS5547 and ADS5527 are 14- and 12-bit ADCs, respectively, supplied in 7 x 7 mm 48-pin QFN packages. Each offers 210 MSPS max performance, with up to 73.3 dBFS SNR and 85 dBc SFDR @ 70 MHz input. Common features include programmable power scaling, parallel CMOS and DDR LVDS output options, as well as selectable output timing and level control. Core power dissipation is 1.0 W, and total power dissipation is 1.2 W.
Original Press Release:
TI Expands High-Speed ADC Portfolio with 14- and 12-bit, 210-MSPS ADCs
New Devices Enable Designers to Choose a High-Performance ADC at the Speed and Resolution the Application Requires
DALLAS (Jan. 16, 2007) - Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced two 14- and 12-bit, 210-MSPS (mega samples per second) analog-to-digital converters (ADCs) to its pin-compatible, high-speed ADS5546 family. The ADS5547 and ADS5527 provide the highest performance at 210 MSPS with up to 73.3-dBFS signal-to-noise ratio (SNR) and 85-dBc spurious-free dynamic range (SFDR) at 70 MHz input frequency . This high performance brings benefits such as better range and resolution for radar and imaging, more accurate power amplifier characterization in digital pre-distortion solutions and higher quality for video and imaging systems. See www.ti.com/sc07010.
The ADS5547 is the fastest 14-bit ADC available while the ADS5527 provides the same speed for customers requiring only 12-bit resolution, both in a small 7-mm x 7-mm leadless package. The addition of the ADS5547 and ADS5527 at this speed, resolution and small size provides designers greater flexibility in component selection. Other benefits include:
· Programmable power scaling
· Low power dissipation: core 1 W, total 1.2 W
· Internal sample and hold
· Parallel CMOS and DDR LVDS output options
· Selectable output timing and level control
· Internal or external reference
· 3.3-V analog and digital supply
· Specified over the industrial temperature range of -40 C to +85 C
Customers can achieve maximum performance by combining the ADS5547 and ADS5527 with a TI high-speed amplifier (such as THS4509 or THS9001), wideband digital down-converter/up-converter (GC5016/8) and clock synchronizer and jitter cleaner (CDCM7005).
Availability and Packaging
Both the ADS5547 and ADS5527 are available now in 48-pin quad flat no-lead (QFN) packages. The ADS5547 is priced at $82.50 each and the ADS5527 is priced at $45.00 each in 1,000-piece quantities. Samples and evaluation modules (EVMs) are available from www.ti.com.
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.
