Content for INA128


The INA128 and INA129 are low-power, general purpose instrumentation amplifiers offering excellent accuracy. The versatile 3-op amp design and small size make these amplifiers ideal for a wide range of applications. Current-feedback input circuitry provides wide bandwidth even at high gain (200 kHz at G = 100). A single external resistor sets any gain from 1 to 10,000. The INA128 provides an industry-standard gain equation; the INA129 gain equation is compatible with the AD620. The INA12x is available in 8-pin plastic DIP and SO-8 surface-mount packages, specified for the –40°C to +85°C temperature range. The INA128 is also available in a dual configuration, the INA2128. The upgraded INA828 offers a lower input bias current (0.6 nA maximum) and lower noise (7 nV/√Hz) at the same quiescent current. See the Device Comparsion Table for a selection of precision instrumentation amplifiers from Texas Instruments.

Thoracic Impedance

“Thoracic Impedance is a measure of the electrical activity in the chest that varies with changes in body size and composition, fluid volume, ventilation status, and heart characteristics such as cardiac output and stroke volume. Our goal was to measure …
