1 With VIN = 0 V to 5 V or 0 V to 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 All specified performance is guaranteed up to 750 kSPS throughout, however throughputs up to 900 kSPS can be used with some linearity performance degradation.
3 Linearity is tested using endpoints, not best fit. All linearity is tested with an external 5 V reference.
4 LSB means least significant bit. All specifications in LSB do not include the error contributed by the reference.
5 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.
6 Conversion results are available immediately after completed conversion.
7 4.75 V or VREF – 0.1 V, whichever is larger.
8 Tested in parallel reading mode.
9 With internal reference, PDREF = PDBUF = low; with internal reference disabled, PDREF = PDBUF = high. With internal reference buffer, PDBUF = low.
10 With all digital inputs forced to OVDD.
