PIN CONFIGURATION AND BLOCK DIAGRAM
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.
