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 = 76.3 µV.

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

5 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.

6 This is the output from the internal band gap.

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

8 Unipolar mode: serial 16-bit straight binary.

Bipolar mode: serial 16-bit twos complement.

9 Conversion results available immediately after completed conversion.

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

11 During acquisition phase.
