ADE7116/ADE7156/ADE7166/ADE7169/ADE7566/ADE7569
62.5mV, 31.3mV
0.25V, 0.125V,
*WHEN DIGITAL INTEGRATOR IS ENABLED, FULL-SCALE OUTPUT DATA IS ATTENUATED
62.5mV, 31.3mV
DEPENDING ON THE SIGNAL FREQUENCY BECAUSE THE INTEGRATOR HAS A –20dB/DECADE
FREQUENCY RESPONSE. WHEN DISABLED, THE OUTPUT IS NOT FURTHER ATTENUATED.
NOT AVAILABLE IN THE ADE7566.
