Overview
The THS4130IDR, produced by Texas Instruments, is a high-performance, fully differential input/output low noise amplifier. This device is part of the THS413x family, fabricated using Texas Instruments' state-of-the-art, high-voltage, complementary bipolar process. It offers excellent common-mode noise rejection and low total harmonic distortion, making it suitable for high-voltage differential signal chains. The amplifier operates over a wide temperature range of –40°C to +85°C and supports a single supply voltage range from 5 V to 30 V or dual supply voltages from ±2 V to ±16.5 V.
