Enables Higher Precision and Design Simplification with Low Noise

Enables Higher Precision and Design Simplification with Low Noise

The S-19760/1 Series achieves low output noise of 28μVRMS (at an output voltage of 2.048V). This feature helps minimize the measurement error of A/D converters that convert sensor signals into digital values. Furthermore, it enables the simplification or reduction of external filter circuits for noise, leading to simplified system design and overall cost reduction.
