A low power zero-drift instrumentation amplifier is said to feature the lowest quiescent current and lowest input bias current versus the nearest competition, as well as an impressive power-to-noise ratio, low offset voltage/drift, and 1.8 V operation. The INA333 improves accuracy and stability while extending battery life in a variety of precision, low-power applications such as portable medical, handheld instrumentation, weigh scales, and data acquisition. The INA333 uses TI's zero-drift technology, which incorporates a proprietary switched-capacitor notch filter to eliminate chopping noise and provide low input voltage noise of 50 nV/rt-Hz.
