SBOS932C January 2020 – March 2021 THP210
The THP210 is designed on a modern bipolar process that features TI's super-beta input transistors. Traditional bipolar transistors feature excellent voltage noise and offset drift, but suffer a tradeoff in high input bias current (IB) and high input bias current noise. Super-beta transistors offer the benefits of low voltage noise and low offset drift with an order of magnitude reduction in input bias current and reduction in input bias current noise. For many filter circuits, input bias current noise can dominate in circuits where higher resistance input resistors are used. The THP210 enables a fully-differential, low-noise amplifier design without restrictions of low input resistance at a power level unmatched by traditional single-ended amplifiers.
