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, visit www.ti.com/ads1293-pr.
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
- Lowest power-consumption to extend battery life:
- Consumes only 300 uW per channel, 85-percent less than
alternative integrated solutions.
- Includes simultaneous digital ECG and pace signals on each
channel; this eliminates the need for a dedicated pace channel,
which reduces power consumption.
- Includes comprehensive built-in error detection with an alarm
pin, relieving the controller from continuously polling for error
conditions.
- Allows independent shutdown on any functional blocks that are
not in use.
- Highly 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.
- System 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.
