Analog To Digital Converters (ADC) FAQ

What is the maximum differential input overdrive tolerance?

The differential input overdrive tolerance is ±(VCC − VEE) volts.

How does SHDR affect the output bit depth?

SHDR optimizes analog gain on a sample-by-sample basis to minimize noise but maintains the 20-bit digital output resolution without changing the bit width.

What is the typical input leakage current?

The typical input leakage current is ±75 pA at 25°C.
