Datasheet

Texas Instruments today introduced an octal, 12-bit, 100-MSPS analog-to-digital converter that provides the lowest power consumption in its class. The ADS5295 uses less than 80 mW per channel, which diminishes board heat and power dissipation in higher-channel-density applications. It incorporates TI’s unique digital processing block, which combines commonly used digital functions to help improve signal-to-noise ratio and filter harmonics while reducing output data rate for narrow-band applications.

The ADS5295 can be used in phase-array architecture systems with higher channel counts, such as ultrasound, security x-ray and non-destructive testing applications.

Key features and benefits of the ADS5295:

•Lowest power per channel for the speed, with low noise: Using only 80 mW-per-channel at 100 MSPS and eight channels, it enables designers to increase channel count without increasing power dissipation high-density applications, while still achieving a low noise of 71 decibel full scale SNR.

•Reduced system cost and complexity: TI’s highly integrated digital processing block integrates commonly used digital functions, such as a low-frequency noise suppression mode, digital filtering options and programmable mapping of low-voltage differential signaling output pins. This lowers FPGA cost and simplifies LVDS output routing, reducing the number of printed circuit board layers and bill of materials cost.

•Reduced interface lines: Outputs data 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 to further reduce FPGA cost.

Tools and support

An evaluation module is available to test the ADS5295 under a variety of conditions. The ADS5295EVM can be purchased today for US$299. An IBIS model to verify board signal integrity requirements is also available.

Availability and pricing

The ADS5295 is available now in an 80-pin HTQFP package for a suggested retail price of US$70 in quantities of 1,000.

Optimized analog products and full portfolio for imaging applications

The ADS5295 joins the ADS529x family, which includes the 14-bit ADS5294 and 12-bit ADS5292. These devices offer eight channels at 80 MSPS, with 77-dBFS and 72-dBFS performance, respectively.
