For a similar device with logic-controlled shutdown,
please refer to the MAX1720/MAX1721. To add manual
shutdown control to the MAX870/MAX871, use the circuit
in Figure 8. The output resistance of the MAX870/
MAX871 will typically be 20Ω plus two times the output
resistance of the buffer driving IN. The 0.1µF capacitor at
the IN pin absorbs the transient input currents of the
MAX870/MAX871.
The output resistance of the buffer driving the IN pin
can be reduced by connecting multiple buffers in par-
allel. The polarity of the shutdown signal can also be
changed by using a noninverting buffer to drive IN.
