Texas Instruments INA103KP Instrumentation Amplifier

The INA103KP is a low-noise, low-distortion instrumentation amplifier from Texas Instruments (Burr Brown lineage) in a 16-pin DIP package, engineered to amplify very small differential signals with high input impedance for precision sensor conditioning. Gain is set with an external RG between pins 2 and 15, with the transfer function G = 1 + 6 kΩ / R_G, enabling gains from 1 up to 1000. The device operates from dual supplies of ±9 V to ±25 V and a temperature range of -40°C to 85°C, with a typical bandwidth of 6 MHz at G = 1 and reduced bandwidth at higher gains. Applications include conditioning signals from sensors, bridge transducers, strain gauges, and other precision measurements in data acquisition, industrial instrumentation, and medical devices.
