3 Description

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.
