|TI INTRODUCES PRECISION, MICRO-POWER OP AMPS FOR BATTERY-POWERED
DALLAS - 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.
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.
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).
