Micro-power op amps keep it quiet
A new family of op amps features high performance single-supply operation, very low quiescent current and low noise relative to the quiescent current.
Texas Instruments has introduced a new family of precision, micro-power op amps from the company's Burr-Brown product line The OPA379 family operates within a 1.8 to 5.5V supply voltage range and features high performance single-supply operation, very low quiescent current (2.9uA) and low noise (80nV/(rt)Hz) relative to the quiescent current

Reference design for wireless optical comms
A new technology from Texas Instruments dramatically cuts the cost and complexity of bringing the high-speed datarates of optical networking to end users.
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 maximum), CMRR (90dB minimum), PSRR (10uV/V maximum) and AOL (100dB minimum) - 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 authorised distributors in SOIC packages.
SOT-23 and SC70 versions will be offered in Q1 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 1000-piece quantities (suggested resale pricing).
