INA163UA Description

Short technical summary and product information.

The INA163UA from Texas Instruments is a highly capable monolithic instrumentation amplifier. It is engineered for exceptional low-noise and low-distortion performance, making it ideal for amplifying weak audio signals, such as those from professional microphone preamps and moving-coil transducers.

 

Key electrical characteristics include a low noise density of 1nV/√Hz at 1kHz and a total harmonic distortion plus noise (THD+N) of just 0.002% at 1kHz with a gain of 100. The amplifier boasts a wide bandwidth of 800kHz at G=100 and operates over a wide supply voltage range of ±4.5V to ±18V. Its high Common Mode Rejection Ratio (CMRR) of over 100dB ensures excellent signal integrity.

 

Designed for flexibility, the gain of the INA163UA is set using an external resistor. It is housed in a space-saving SO-14 surface-mount package and is specified for operation across a temperature range of -40°C to +85°C. This makes it a robust choice for demanding industrial, instrumentation, and medical applications where precise signal amplification is critical.
