Description
Input and Output Stage Positive Supply Voltage. 4.5 V − 5.5 V.
Differential Inputs
Chip Enable. Pull high to enable.
Input and Output Stage Common. Connect via lowest possible impedance to external circuit
common
Vpos/2 Reference Output Decoupling. Connect decoupling capacitor to circuit common.
Output Offset Correction Loop Compensation. Connect capacitor to circuit common. Tie to
common to disable.
Output Common-mode Centering Loop Compensation. Connect capacitor to circuit common
Output Common-mode Setpoint. Defaults to Vpos/2 if left open
Differential Outputs
Data enable . Pull high to address each or both channels for parallel load. Not used in serial mode.
Parallel data path for SENB pulled low. For SENB pulled high, BIT0 becomes a chip-select (CS), BIT1
becomes serial data input, SDAT, and BIT2 becomes serial clock, SCLK. BIT3-BIT5 are not used in
the serial mode
Serial interface enable. Pull high for serial; pull low for parallel.
