The INA103/INA104 is a low-cost, high-precision instrumentation amplifier that requires only one external resistor to set the gain from 1 to 10,000. Available in MSOP-8 and SOIC-8 packages, the INA103/INA104 features low standby power consumption (only 1.3mA), making it highly suitable for battery-powered mobile devices. The INA103/INA104 is a high-precision instrumentation amplifier with low non-linearity of only 0.8ppm and a maximum input offset voltage of 20μV, making it an ideal choice for high-precision data acquisition systems, especially in measurement instruments and sensor interfaces. Moreover, the low noise, low input bias current, and low power consumption of the INA103/INA104 make it highly suitable for medical applications such as ECG and blood pressure monitors. With low noise characteristics of 17nV/√Hz @ 1kHz, 1.8μV<sub>P-P</sub> from 0.1Hz to 10Hz, and 0.45pA/√Hz noise current, the INA103/INA104 is an excellent choice for preamplification.
