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

Posted on: Monday, 27 March 2006, 09:00 CST

DALLAS, March 27 /PRNewswire/ -- Texas Instruments Incorporated (TI) 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.
