The MAX680/MAX681 are monolithic, CMOS, dual charge-pump voltage converters that provide ±10V out-puts from a +5V input voltage. The MAX680/MAX681 pro- vide both a positive step-up charge pump to develop +10V from +5V input and an inverting charge pump to generate the -10V output. Both parts have an on-chip, 8kHz oscillator. The MAX681 has the capacitors internal to the package, and the MAX680 requires four externalcapacitors to produce both positive and negative voltages from a single supply.
The output source impedances are typically 150Ω, pro-viding useful output currents up to 10mA. The low quies-cent current and high efficiency make thidevice suitable or a variety of applications that need both positive and negative voltages generated from a single supply.
The MAX864/MAX865 are also recommended for new designs. The MAX864 operates at up to 200kHz and uses smaller capacitors. The MAX865 comes in the smaller µMAX package.

The MAX680/MAX681 can be used wherever a single positive supply is available and where positive and nega- tive voltages are required. Commoapplications include generating ±6V from a 3V battery and generating ±10V from the standard +5V logic supply (for use with analog circuitry). Typical applicationsinclude:
±6V from 3V Lithium Cell
Hand-Held Instruments
Data-Acquisition Systems
Panel Meters
±10V from +5V Logic
