Semiconductor developer, Texas Instruments has added to its rail-to-rail input and output, 1.8-V operational amplifier portfolio, the OPA2314.
The dual amplifier is designed for a battery-powered, low-voltage, cost-sensitive consumer, medical and industrial applications. The new optional amplifier OPA2314 offers the desired combination of performance and power with low noise, low quiescent current. Designed to utilize up to 40% less quiescent current than other products available in the market, the device extends the battery life of blood glucose meters, carbon monoxide and smoke detectors, laptops, portable media players and computer peripherals.
A low quiescent current of 190 uA/channel combined with low noise of 14 nV/Hz at one kilohertz allows the OPA2314 amplifier to reduce the power consumption, maintain the signal-to-noise ratio while providing signal amplification. Operational with rail-to-rail I/O swings, the OPA2314 is functional with a low voltage supply of 1.8 V and up to a supply of 5.5 V, thus extending the amplifier's dynamic I/O range. High sensitivity can be achieved due to the wide gain bandwidth of 3 MHz gain. An input bias current of just 0.2 pA allows the OPA2314 to support applications with high source impedance.
Available in three package options, the OPA2314 is available along with software for calculation, application and analysis including FilterPro and Analog Filter Designer. Additionally, Texas Instruments will support the OPA2314 with calculators for wavelength/frequency and decibel.
