Full-Scale Error  
Notes: 1. Bipolar Offset Errors and Full-Scale Gain Errors for the current and voltage channels refer to the respective Irms  
Register and Vrms Register output, when the device is operating in ‘continuous computation cycles’ data acquisition  
mode, after offset/gain system calibration sequences have been executed. These specs do not apply to the error  
of the Instantaneous Current/Voltage Register output.  
2. Specifications guaranteed by design, characterization, and/or test.  
3. Analog signals are relative to VA- and digital signals to DGND unless otherwise noted.  
4. In requiring VA+ = VD+ =5 V 10%, note that it is allowable for VA+, VD+ to differ by as much as 200 mV, as long  
as VA+ > VD+.  
5. Note that “Sps” is an abbreviation for units of “samples per second”.  
6. Effective Input Impedance (Zin) is determined by clock frequency (DCLK) and Input Capacitance (IC).  
Zin = 1/(IC*DCLK/4). Note that DCLK = MCLK / K.
