The JFET input stage delivers 50 pA input bias current, which preserves accuracy when driving high-impedance sources like piezoelectric sensors or photodiodes.
Commercial temperature range — deployment boundary
It is not specified for industrial or automotive environments where the ambient temperature drops below freezing or exceeds 70°C. If the board sees a cold start in an unheated enclosure or sits near a motor drive, this is the wrong temperature grade.
That output current is enough to drive a line-level audio load or a 10 kΩ ADC input, but it will not drive a headphone or relay directly.
