TI Introduces Precision, Micro-Power Op Amps for Battery-Powered Applications

Nov 28, 2005

DALLAS (December 28, 2005) - Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced a new family of precision, micro-power operational amplifiers (op amps) from the company's Burr-Brown product line. The OPA379 family operates within a 1.8V to 5.5V supply voltage range and features high performance single-supply operation, very low quiescent current (2.9uA) and low noise (80nV/rtHz) relative to the quiescent current. The micro-size packages make the devices ideal for battery-powered applications. (See www.ti.com/sc05223.)

This unique product family offers an impressive unity gain bandwidth/quiescent current ratio of 90kHz on 2.9uA and has significantly lower noise than products with similar current consumption. The combination of DC precision specifications -- Vos (1.5mV max), CMRR (90dB min), PSRR (10uV/V max) and AOL (100dB min) -- make this product family very attractive for designs requiring precision with low power consumption.
The reduced package size of the OPA379 allows compact designs in a variety of applications including designs with TI's MSP430 low-power microcontrollers, as well as handheld medical instruments, remote sensors, gas detection and wireless metering.

Available Today

The OPA379 (single) and OPA2379 (dual) are available now from TI and its authorized distributors in SOIC packages. SOT-23 and SC70 versions will be offered in 1Q 2006, along with a quad version, the OPA4379 in a TSSOP package. The single and dual versions are priced at $0.75 and $1.10 respectively 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.
