ICL7660 DIP-8 INTERSIL CMOS VOLTAGE CONVERTERS IC NEW

The ICL7660 are monolithic, CMOS
switched-capacitor voltage converters that invert, double,
divide, or multiply a positive input voltage. They are
pin compatible with the industry-standard ICL7660 and
LTC1044. Operation is guaranteed from 1.5V to 10V with
no external diode over the full temperature range. They
deliver 10mA with a 0.5V output drop. The MAX1044 has
a BOOST pin that raises the oscillator frequency above
the audio band and reduces external capacitor size
requirements.
The MAX1044/ICL7660 combine low quiescent current and
high efficiency. Oscillator control circuitry and four power
MOSFET switches are included on-chip. Applications
include generating a -5V supply from a +5V logic supply
to power analog circuitry. For applications requiring more
power, the MAX660 delivers up to 100mA with a voltage
