Overview
The THP210, produced by Texas Instruments, is an ultra-low-offset, high-voltage, low-noise, precision fully-differential amplifier (FDA). This device is designed to provide exceptional offset, low noise, and low total harmonic distortion (THD), making it ideal for signal conditioning circuits. The THP210 features Texas Instruments' super-beta bipolar input devices, which yield a very-low noise figure at low quiescent current and input bias current. It is particularly useful in applications requiring high signal-to-noise ratio (SNR) and low power consumption.
