The dual OPA2314 op amp provides the best combination of power and performance, with low quiescent current, low noise and a wide 1.8-V to 5.5-V supply range. The device 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 Include:
- Best combination of power and performance: Low maximum quiescent current of 190 µA 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.
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.
