190 uA quiescent current, 14 nV/rtHz at 1 kHz noise, 1.8V to 5.5V voltage range op-amps

Texas Instruments Incorporated (TI) has expanded its 1.8-V, rail-to-rail input and output, general-purpose operational amplifier (op amp) portfolio with the dual OPA2314 op amp for low-voltage, battery-powered, cost-sensitive industrial, consumer and medical applications. TI claims these devices uses up to 40 percent less quiescent current compared to its closest competitor to extend the battery life of smoke and carbon monoxide detectors, portable media players, laptops, computer peripherals and blood glucose meters.

Key features and benefits as per TI include:
Best combination of power and performance: Low maximum quiescent current of 190 uA per channel and low noise of 14 nV/rtHz at 1 kHz enables low-level signal amplification while maintaining a high signal-to-noise ratio and reducing system power consumption.
Widest supply range: Operates from 1.8 V to 5.5 V with rail-to-rail input and output swings. This extends the dynamic input and output range of the amplifier to maintain or improve the signal chain's signal-to-noise ratio.
High gain bandwidth: 3-MHz gain bandwidth provides high sensitivity to enable high-resolution systems across a wide frequency range.
Low input bias: 0.2-pA input bias current supports high source impedance applications.


Availability and pricing: The OPA2314 is available now in three package options: 3-mm x 3-mm SON, 5-mm x 3-mm MSOP, 6-mm x 5-mm SOIC. Suggested retail-pricing starts at $0.55 for 1,000-unit quantities. Single and quad-channel versions will be available in fourth quarter.
