An exciting feature of the AD826 is its ability to perform well in a
single supply configuration (see Figure 37). The AD826 is ideally
suited for applications that require low power dissipation and high
output current and those which need to drive large capacitive
loads, such as high speed buffering and instrumentation.
Referring to Figure 36, careful consideration should be given to
the proper selection of component values. The choices for this
particular circuit are: (R1 + R3) R2 combine with C1 to form a
low frequency corner of approximately 30 Hz.
PARALLEL AMPS PROVIDE 100 mA TO LOAD
By taking advantage of the superior matching characteristics of
the AD826, enhanced performance can easily be achieved by
employing the circuit in Figure 38. Here, two identical cells are
paralleled to obtain even higher load driving capability than that
of a single amplifier (100 mA min guaranteed). R1 and R2 are
included to limit current flow between amplifier outputs that
would arise in the presence of any residual mismatch.
