1 See the Analog Inputs section.

2 The bandwidth is set with the configuration register

3 LSB means least significant bit. With the 5 V input range, one LSB is 76.3 μV.

4 See the Terminology section. These specifications include full temperature range variation but not the error contribution from the external reference.

5 With VDD = 5 V, unless otherwise noted.

6 All specifications expressed in decibels are referred to a full-scale input FSR and tested with an input signal at 0.5 dB below full scale, unless otherwise specified.

7 This is the output from the internal band gap.

8 The output voltage is internal and present on a dedicated multiplexer input.

9 Unipolar mode: serial 16-bit straight binary.

Bipolar mode: serial 16-bit twos complement.

10 Conversion results available immediately after completed conversion.

11 With all digital inputs forced to VIO or GND as required.

12 During acquisition phase.
