Precision Amps leading technologies
Technologies to improve offset and drift:
Amplifiers with zero-drift technology employ a unique, self-correcting technology which provides ultra-low input offset voltage (Vos) and near-zero input offset voltage drift over time and temperature (dVos/dT) suitable for precision applications.
e-Trim™ is TI’s patented post package trimming architecture. Correction current sources internal to the devices are adjusted during the final package-level manufacturing test. Once the trimming is completed, the gateway to trim circuitry is closed, so the trim control circuit is disabled and the adjustments become permanent.
Technology to enable faster data acquisition:
TI has developed a new input circuitry for high voltage CMOS inputs which does not require the antiparallel diodes for device protection. This technology minimizes the leakage current which in turn helps the amplifier settle faster.
Technologies to improve input bias current, input offset current and input current noise:
TI’s Super Beta provides excellent matching of the transistors in the input differential pair. Along with offset trim methodologies, op amps with Super Beta have a very low offset voltage, offset drift and input bias current. Thanks to a very low input bias current, the current noise density is much lower and the input impedance is much higher than any other bipolar technology, including op amps with input bias cancellation circuits.
JFET Dielectric isolation
Thanks to a buried isolation layer between the n-type and p-type, TI’s JFET amplifiers provide unprecedented performance for low noise and low distortion circuits
Technology to ensure high linearity across entire common-mode range:
Zero-crossover amplifiers employ a unique topology which eliminates the error induced by the crossover region that standard rail-to-rail amplifiers have. TI’s zero-crossover topology assures high linearity across the entire common-mode voltage range and lowest distortion for precision and general applications.
