The INA333 zero-drift instrumentation amplifier provides, according to the company, the lowest quiescent current (75 μA) and the lowest input bias current (200 pA) compared to the nearest competition. Consequently, the company also claims an impressive power-to-noise ratio, a very low offset voltage of 25 μV, offset drift of 0.1 μV/℃, and 1.8-V operation - improving accuracy and stability while extending battery life in a variety of precision, low-power applications such as portable medical, data acquisition, weighing, and handheld instrumentation.
