NOTES

1Operating temperature range: A Version: –40

°C to +85°C.

2Unmeasurable: sigma-delta conversion is inherently free of differential nonlinearities.

3See terminology.

4Change in reference voltage due to a change in Tx SLEEP or Rx SLEEP modes.

5Measured while the digital inputs to the transmit interface are static.

6Measured while the digital inputs to the receive interface are static.

7Measured while the digital inputs to the auxiliary interface are static.
