PRODUCTION DATA
The full-scale input-range (FSR) pin selects whether the full-scale input range for both the I channel and Q channel is higher (logic-high) or lower (logic-low). The input full-scale range is specified as VIN_FSR in Converter Electrical Characteristics: Digital Control and Output Pin Characteristics. In non-ECM, the full-scale input range for each I and Q channel may not be set independently, but it is possible to do so in ECM. The device must be calibrated following a change in FSR to obtain optimal performance.
To use this feature in ECM, use the I- and Q-channel Full Scale Range Adjust registers (Addr: 3h and Bh, respectively). See Input Control and Adjust for more information.
