AWA14601 Wideband TEDS-Enabled Preamplifier

Reference-grade measurement accuracy: ultra-wide, flat frequency response combined with near-zero insertion loss and ultra-low distortion make it suitable for high-precision acoustic metrology and calibration work

Low-noise performance for weak signal detection: microvolt-level self-noise enables accurate measurement of very low sound pressure levels

High dynamic range: strong output drive capability (≥10 Vrms) supports measurement of high-level acoustic events without clipping

Robust environmental adaptability: extended temperature range with tight accuracy tolerances ensures reliable performance in harsh field and industrial conditions

Ideal for demanding applications: well-suited for high-end acoustic research, precision noise/vibration testing, environmental monitoring, and standards-compliant calibration laboratories
