VSS GENERATION
Operating the AD7225 from dual supplies results in enhanced
performance over single-supply operation on a number of
parameters as previously outlined. Some applications may
require this enhanced performance, but may only have a single
power supply rail available. The circuit of Figure 29 shows a
method of generating a negative voltage using one CD4049,
operated from a VDD of 15 V. Two inverters of the hex inverter
chip are used as an oscillator. The other four inverters are in
parallel and used as buffers for higher output current. The
square wave output is level translated to a negative-going signal,
then rectified and filtered. The circuit configuration shown
provides an output voltage of 5.1 V for current loadings in the
range of 0.5 mA to 9 mA. This satisfies the AD7225 ISS require-
ment over the commercial operating temperature range.
