The INA166 is a low-noise, low-distortion, G = 2000 instrumentation amplifier. It has a wide bandwidth and excellent dynamic response, making it ideal for amplifying low-level signals such as microphones or hydrophones. Many industrial, instrumentation, and medical applications also benefit from its low noise and wide bandwidth.
The INA166 instrumentation amplifier provides very low noise (1.3 nV/√Hz at 1 kHz) and low total harmonic distortion (0.09 % at 1 kHz). Its current‑feedback architecture yields a wide bandwidth of 450 kHz and a fixed gain of 2000, making it suitable for microphone, hydrophone, and other low‑level signal applications.
The device is offered in a SO‑14 surface‑mount package and operates from a supply range of ±4.5 V to ±18 V. Detailed specifications, typical performance curves, and packaging information are provided in the document.
