PRODUCTION DATA
The power-down I-channel (PDI) pin selects whether the I channel is powered down (logic-high) or active (logic-low). The digital data output pins, DI and DId, (both positive and negative) are put into a high impedance state when the I channel is powered down. Upon return to the active state, the pipeline contains meaningless information and must be flushed. The supply currents (typicals and limits) are available for the I channel powered down or active and may be found in Converter Electrical Characteristics: Power Supply Characteristics. Recalibrate the device following a power-cycle of PDI (or PDQ).
The PDI pin remains active in ECM, and either the PDI pin or the PDI bit of the Configuration Register (Addr: 0h; Bit: 11) may be used to power-down the I channel. See Power Down for more information.
