- Accuracy independent of input source impedances.
- High input impedance of 1012 Ω.
- Inherently filters and integrates any external noise spikes.
- Differential analog input.
- Wide bipolar analog input voltage range ±3.5V.
- Automatic zero offset compensation.
- Low linearity error - as low as 0.002%.
- Fast zero-crossing comparator - 1µs.
- Low power dissipation.
