The TC7117/TC7117A are designed to operate from
±5V supplies. However, if a negative supply is not avail-
able, it can be generated with a TC7660 DC-to-DC con-
verter and two capacitors. Figure 5-1 shows this
application.
In selected applications, a negative supply is not
required. The conditions for using a single +5V supply
are:
