• Manufacturer Part Number: MAX871
• Description: Switched-Capacitor Voltage Inverters
• Manufacturer: MAXIM [Maxim Integrated Products]

If shutdown control is necessary, use the circuit in
Figure 8. The output resistance of the MAX870/MAX871
will typically be 20Ω plus two times the output resis-
tance 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.
Maxim cannot assume responsibility for use of any circuitry other than circuitry entirely embodied in a Maxim product. No circuit patent licenses are
implied. Maxim reserves the right to change the circuitry and specifications without notice at any time.
