1

The LSB unit means least significant bit. The weight of the LSB, referred to input, changes depending on the input voltage range. See the Programmable Gain section

for the LSB size.

2

Full-scale differential input ranges of ±2.56 V, ±5.12 V, ±10.24 V, and ±20.48 V are set by the configuration register.

3

If using the external multiplexer in front of the ADAS3023, it must be switched at least 820 ns prior to the rising edge of CNV.

4

See the Terminology section. These parameters are specified at ambient temperature with an external reference. All other influences of temperature and supply are

measured and specified separately.

5

All ac specifications expressed in decibels are referenced to the full-scale input range (FSR) and are tested with an input signal at 0.5 dB below full scale, unless

otherwise specified.

6

This is the output from the internal band gap reference.

7

There is no pipeline delay. Conversion results are available immediately after a conversion is completed.
