DALLAS, Sept. 8, 2011 /PRNewswire/ -- Texas Instruments
Incorporated (TI) (NYSE: TXN) today expanded its 1.8-V,
rail-to-rail input and output, general purpose operational
amplifier (op amp) portfolio with the first in a new line of op
amps for low-voltage, battery-powered, cost-sensitive industrial,
consumer and medical applications. 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 5.5V 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. For more information and to
order OPA2314 samples, visit www.ti.com/opa2314-pr.
Key features and benefits
- 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.
Tools and support
TI offers a variety of free tools and support to speed
development with the OPA2314, including:
- A universal evaluation module (EVM) that simplifies evaluation
by allowing many different circuits to be constructed easily and
quickly. The EVM is available today for $5.
- A SPICE model in TINA-TI 9.1, a SPICE-based analog simulation
program. Download TINA-TI 9.1 at
www.ti.com/tina-ti-download-pr.
- Software for analysis, application and calculation utilities,
including Analog Filter Designer, FilterPro, and calculators for
decibel, frequency/wavelength and op amp gain stage.
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.
