TI präsentiert bestes Rauschverhalten und geringste Leistungsaufnahme in einem achtkanaligen 14-Bit-ADC mit 80 MSPS für bildgebende medizinische Applikationen
TI offers best noise performance and lowest power in 14-bit, 8-channel ADC at 80 MSPS for medical imaging applications
Key features and benefits
-Leading noise and power performance: The ADS5294 provides best-in-class SNR and enables designers of high-density applications to increase channel count without increasing power.
-75.5 dBFS SNR at 5 MHz/80 MSPS
-78.2 dBFS SNR at 5 MHz and decimation filter enabled
-84 dBc SFDR at 5 MHz/80 MSPS
-77 mW per channel at 80 MSPS (two LVDS wires per channel)
-Low-frequency noise suppression mode.
-Digital processing block that integrates several commonly used system functions such as two- or four-channel averaging and decimation by two, four or eight filters.
-The digital processing block can be used to significantly improve SNR and filter harmonics, while reducing output data rate for narrow-band applications.
-Two-wire LVDS interface: Using the ADS5294, digital data can be output over one or two wires of LVDS pins per channel reducing the number of interface lines. This creates a two-wire interface which keeps the serial data rate low allowing designers to use low cost FPGAs.
-In addition to medical imaging systems, the ADS5294 brings the same benefits to radar, communications, test and measurement and other multi-channel data acquisition applications.
Availability, packaging and pricing
The ADS5294 is available now in a 12-mm x 12-mm, 80-pin QFP package. The ADS5294 is priced at $84 in quantities of 1,000.
Tools and support
To provide a flexible environment for testing the ADS5294 under a variety of conditions, an evaluation module (EVM) is available. The ADS5294 EVM is priced at $299 and can be found at www.ti.com/ads5294evm-pr.
An IBIS model to verify board signal integrity requirements is available at www.ti.com/ads5294model-pr.
