NOTES
1
Operating temperature range: A Version: –40°C to +85°C.
2
Unmeasurable: sigma-delta conversion is inherently free of differential nonlinearities.
3
See terminology.
4
Change in reference voltage due to a change in Tx SLEEP or Rx SLEEP modes.
5
Measured while the digital inputs to the transmit interface are static.
6
Measured while the digital inputs to the receive interface are static.
7
Measured while the digital inputs to the auxiliary interface are static.
Specifications subject to change without notice.
