THP210DR

The THP210 is an ultra-low offset voltage, low-noise, high-voltage, precision, fully differential amplifier that can easily filter and drive fully differential signal chains. The THP210 can also be used to convert single-ended sources to the differential outputs required by high-resolution analog-to-digital converters (ADCs). The bipolar super ß inputs are designed to achieve excellent offset voltage, low noise, and THD, and can produce extremely low noise figures at extremely low quiescent and input bias currents. This device is designed for signal conditioning circuits that require low offset voltage and power consumption, as well as high signal-to-noise ratio (SNR). The THP210 features high-voltage power supply capabilities, supporting supply voltages up to ±18V. This feature allows high-voltage differential signal chains to increase headroom and dynamic range without adding a separate amplifier for each polarity of the differential signal. The extremely low voltage and current noise make the THP210 suitable for high-gain configurations with minimal impact on signal fidelity.
