The THP210 is an ultra-low-offset, low-noise, high-voltage, precision, fully differential amplifier that easily filters and drives fully differential signal chains. The THP210 is also used to convert single-ended sources to differential outputs as required by high-resolution analog-to-digital converters (ADCs). Designed for exceptional offset, low noise and THD, the bipolar super-beta inputs yield a very-low noise figure at very-low quiescent current and input bias current. This device is designed for signal conditioning circuits where low power offset and power consumption are required, along with excellent signal-to-noise ratio (SNR).

The THP210 features high-voltage supply capability, allowing for supply voltages up to ±18 V. This capability allows high-voltage differential signal chains to benefit from the improved headroom and dynamic range without adding separate amplifiers for each polarity of the differential signal. Very-low voltage and current noise enables the THP210 for use in high-gain configurations with minimal impact to the signal fidelity.
