1 See the Analog Inputs section.
2 The bandwidth is set in 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.
