1 With VIN = unipolar 5 V or unipolar 10 V ranges, the input current is typically 70 μA. In all input ranges, the input current scales with throughput. See the Analog Inputs section.
2 Linearity is tested using endpoints, not best fit. All linearity is tested with an external 5 V reference.
3 LSB means least significant bit. All specifications in LSB do not include the error contributed by the reference.
4 All specifications in decibels are referred to a full-scale range input, FSR. Tested with an input signal at 0.5 dB below full-scale, unless otherwise specified.
5 Conversion results are available immediately after completed conversion.
6 4.75 V or VREF – 0.1 V, whichever is larger.
7 Tested in parallel reading mode.
8 With internal reference, PDREF = PDBUF = low; with internal reference disabled, PDREF = PDBUF = high. With internal reference buffer, PDBUF = low.
9 With all digital inputs forced to OVDD.
10 Consult sales for extended temperature range.
