Texas Instruments Inc. (TI) introduced a new family of precision, micro-power operational amplifiers from its 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, 2.9?A quiescent current and 80nV/rtHz noise.

According to the press release, the new product family offers an impressive unity gain bandwidth/quiescent current ratio of 90kHz on 2.9?A and has significantly lower noise than products with similar current consumption. The combination of DC precision specificationsVos (1.5mV max), CMRR (90dB min), PSRR (10?V/V max) and AOL (100dB min)make this product family suitable for designs requiring precision with low power consumption.

Additionally, 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. TI added that the amplifier's micro-power operation helps preserve precision by keeping the chip temperature low as the power is easily dissipated through the exposed pad.

The OPA379 (single) and OPA2379 (dual) are available 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. In 1,000-piece quantities, the single and dual versions have suggested resale pricings of 75 cents and $1.10, respectively.
