DESCRIPTION

Calogic CLM7660 DC-to-DC converter will generate a negative

voltage from a positive source. The CLM7660 generates -5V

in +5V digital systems and with two external capacitors, the device

will convert a 1.5V to 10V input signal to a -1.5V to -10V level.

Applications include analog-to-digital converters, digital-to-analog

converters, operational amplifiers and multiplexers. Many of these

systems require negative supply voltages. The CLM7660 allows

+5V digital logic systems to incorporate these analog components

without an additional main power source. Lower part count, less real

estate, ease of use are just a few of the benefits of the CLM7660.
