With V
IN
= 0 V to 5 V or 0 V to 10 V ranges, the input current is typically 40 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 dB 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.

– 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.
