Texas Instruments INA163 Low-Noise Low-Distortion Instrumentation Amplifier INA163UAE4

The INA163 is a low-noise, low-distortion instrumentation amplifier designed for high-performance applications. It features a voltage noise of 1nV/,àöHz at 1kHz and a total harmonic distortion plus noise (THD+N) of 0.002% at a gain of 100. The amplifier supports a wide bandwidth of 800kHz at this gain, making it suitable for low-level audio signals and various industrial and medical applications. The INA163 operates over a supply voltage range of ¬±4.5V to ¬±18V and offers high common-mode rejection (CMR) greater than 100dB. Gain can be set using an external resistor, allowing flexibility in application design. It is housed in a compact SO-14 surface-mount package and is specified for operation within a temperature range of -40¬8C to +85¬8C. This amplifier is particularly effective in professional microphone preamps and differential receiver applications, providing superior performance in low-impedance environments.
