Measurement error = (Energy Measured By Device - True Energy)/True Energy * 100%. Accuracy is
measured with signal (±660 mV) on Channel 1. F OUT0 , F OUT1 pulse outputs. Valid from 45 Hz to 65 Hz.
See Section 2.0 “Typical Performance Curves” for higher frequencies and increased dynamic range.
Does not include internal V REF . Gain = 1, CH0 = 470 mVDC, CH1 = 660 mVDC, difference between
measured output frequency and expected transfer function.
Percent of HF OUT output frequency variation; Includes external V REF = 2.5V, CH1 = 100 mVRMS @
50 Hz, CH2 = 100 mVRMS @ 50 Hz, AV DD = 5V + 1V pp @ 100 Hz. DC PSRR: 5V ±500 mV.
Error applies down to 60° lead (PF = 0.5 capacitive) and 60° lag (PF = 0.5 inductive).
Refer to Section 4.0 “Device Overview” for complete description.
Specified by characterization, not production tested.
1 MCLK period at 3.58 MHz is equivalent to less than <0.005 degrees at 50 or 60 Hz.
Gain error match is measured from CH0 G = 1 to any other gain setting.

The MCP3905/06 operate over this extended temperature range, but with reduced performance. In any
case, the Junction Temperature (T J ) must not exceed the Absolute Maximum specification of +150°C.
