MAX680/MAX681
+5V to ±10V Voltage Converters
General Description
The MAX680/MAX681 are monolithic, CMOS, dual chargepump voltage converters that provide ±10V outputs from a +5V input voltage. The MAX680/MAX681 provide 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 external capacitors to produce both positive and negative voltages from a single supply.
The output source impedances are typically 150Ω, providing useful output currents up to 10mA.
