PRODUCTION DATA
The RANGE pin is a digital input pin that allows the input range to be selected for all analog input channels. If this pin is set to logic high, then the device is configured to operate in the ±10-V input range for all input channels. If this pin is set to logic low, then all input channels operate in the ±5-V input range.
In applications where the input range remains the same for all input channels, the RANGE pin is recommended to be hardwired to the appropriate signal. However, some applications can require an on-the-fly change in the input range by the digital host. For such cases, the RANGE pin functions as an asynchronous input, meaning that any change in the logic input results in an immediate change in the input range configuration of the device. An additional 100 µs must typically be allowed in addition to the device acquisition time for the internal active circuitry to settle to the required accuracy before initiating the next conversion.
The RANGE pin is also used to put the device in standby or shutdown mode depending on the state of the STBY input pin, as explained in the Power-Down Modes section.
