Texas Instruments has expanded its 1.8V, rail-to-rail input and output, general purpose op amp portfolio with the first in the recent line of op amps for low-voltage, battery-powered, industrial, consumer and medical applications. The dual OPA2314 op amp extends the battery life of smoke and carbon monoxide detectors, portable media players, laptops, computer peripherals and blood glucose metres.
The op amp provides quiescent current of 190µA per channel and noise of 14nV/rtHz at 1kHz enables low-level signal amplification while maintaining a high signal-to-noise ratio and reducing system power consumption, claims the company. The op amp operates from 1.8 to 5.5V with rail-to-rail input and output swings. It features 3MHz gain bandwidth to enable high-resolution systems across a wide frequency range and provides 0.2pA input bias current.
The company offers many tools and support to speed development with the op amp, including: an EVM (universal evaluation module), a SPICE (simulation program with IC emphasis) model in TINA-TI 9.1, a SPICE-based analogue simulation program and software for analysis, application and calculation utilities, including analogue filter designer, filterpro, and calculators for decibel, frequency and wavelength, and op amp gain stage.
The op amp is available in three package options such as 3x3mm SON (small-outline no leads), 5x3mm MSOP (mini small outline plastic packages), and 6x5mm SOIC.
