DALLAS, Nov. 28, 2012

DALLAS, Nov. 28, 2012 /PRNewswire/ --Texas Instruments Incorporated (TI)
(NASDAQ: TXN) expanded its award-winning ADS1298 analog-front-end (AFE) family
today with the industry's most power-efficient 24-bit, 3-channel AFE for
biopotential measurement applications, such as portable, battery-powered
electrocardiogram (ECG) solutions, Holter monitors and wireless patient
monitoring equipment. The ADS1293 is also the first device in the family that
can support one to five leads with a single AFE to significantly reduce the
size, power consumption and overall cost of scalable medical instrumentation
systems. Each channel of the ADS1293 can be independently programmed for a
specific sample rate and bandwidth, allowing customers to optimize the
configuration for performance and power. For information or to order samples,

In addition to the ADS1293, the company unveiled WEBENCH® Medical AFE
Designer, the latest addition to TI's growing family of WEBENCH design tools.
WEBENCH Medical AFE Designer simplifies and speeds system design with the
ADS1293, enabling customers to design and configure the AFE online. They can
then download configuration data to the ADS1293 evaluation module (EVM),
reducing design time from weeks or months to a matter of minutes.

Key features and benefits of the ADS1293

  oLowest power-consumption to extend battery life:

       oConsumes only 300 uW per channel, 85-percent less than alternative
         integrated solutions.
       oIncludes simultaneous digital ECG and pace signals on each channel;
         this eliminates the need for a dedicated pace channel, which reduces
         power consumption.
       oIncludes comprehensive built-in error detection with an alarm pin,
         relieving the controller from continuously polling for error
       oAllows independent shutdown on any functional blocks that are not in

  oHighly integrated to simplify design, reduce board space: Optimizes signal
    path gain stages, which eliminates the need for analog filters and reduces
    board space requirements, by integrating three 24-bit delta sigma
    analog-to-digital converters (ADCs), four low-noise instrumentation
    amplifiers and EMI-hardened inputs, right leg drive amplifier, lead-off
    detection, and Wilson and Goldberger terminals.
  oSystem design flexibility: Programmable settings for DC and AC lead-off
    detection to increase design flexibility.

Tools and support
The ADS1293EVM can be purchased today for US$99. This evaluation module's
development tool provides a user-friendly graphical user interface (GUI) with
an interactive block diagram, which allows designers to try different system
configurations with the chip quickly and easily. ECG and pace data can also be
captured and saved for post processing. The ADS1293 development tool is also
available online in the WEBENCH® Medical AFE Designer.

Customers can also ask questions and get answers from TI experts in the
Precision Analog Data Converter Forum in the TI E2E™ Community.

Availability and packaging
The ADS1293 is available today in a 5-mm x 5-mm QFN package for US$5.50 in
1,000-unit quantities.
