Texas Instruments Introduces Analog Current/Voltage Output Driver for Industrial Applications

March 28, 2006

    BEIJING, March 28 /Xinhua-PRNewswire/ -- Texas
Instruments Incorporated (TI) (NYSE: TXN) today announced a
digitally-controlled current/voltage output driver for
industrial applications such as industrial PLC
(programmable logic controller) and process control
equipment.  The XTR300 delivers outputs up to +/-17V and
+/-24mA, handling virtually any standard analog signaling
requirements.  Digital selection of voltage or current
output eliminates bulky discrete circuitry and awkward
pin-strapped configuration schemes.  (See
http://www.ti.com/sc06067 )

    Internal fault detection circuitry in the XTR300
provides digital indication of line/load faults, including
shorts or opens in cable or remotely-located loads.  To
sense output voltage, the device includes an
instrumentation amplifier which can be connected for 4-wire
load connections to accurately control the voltage at
remotely-located loads.  The instrumentation amplifier can
also be used as a general purpose analog input.
In addition, the XTR300 can be configured for 3-wire
industrial sensor applications.  It requires no external
output transistors.  The 5mm x 5mm QFN package allows power
to be dissipated through a bottom-side power pad with low
thermal resistance.  The XTR300 operates from power
supplies up to +/-20V and is specified over the -40C to 85C
industrial temperature range.  Chip fabrication is on a
proprietary BiCMOS process.

    Available Today	

    The XTR300 is available now in a 5mm x 5mm, QFN-20
package from TI and its authorized distributors.  The
device is priced at $2.45 in 1,000 piece quantities
(suggested resale pricing). 

    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.  For more information on TI's
