The following is a list of known issues with the first revision
of the ADE7753 silicon (rev 1.0). These issues will be solved
in the next version. Samples of this version of the silicon can
be identified from the branding on the top face of the package.
The branding is shown below:

1. On-Chip Voltage Reference
Currently the on-chip voltage reference has a nominal volt-
age of 2.2V. The temperature drift has a large drift at
approximately 900ppm/°C.

2. VAEHF and VAEOF of the Interrupt Status Register
The VAEHF and VAEOF bits are set when the content of the
VAENERGY register reaches a quarter and half of its
maximum value. VAENERGY is an unsigned, 24-bit
register.

At low current, if the value of IRMSOS is set to a large
negative value, the output of the IRMS register can become
unstable.
