3 Description
The THP210 is an ultra-low-offset, low-noise, highvoltage,
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 highgain
configurations with minimal impact to the signal
fidelity.
