• Breadboarding Suggestions
• Do all wiring with power off.
• Wire the V and V supply leads first to the
  op amp or Vcc and Gnd to TTL ICs.
• For Analog Design, try to wire all ground
  leads to one tie point, the power supply common.
• This type of connection is called star
  grounding. Do not use a ground bus, because you
  may create a ground loop, thereby generating
  unwanted noise voltages.
• Double-check the wiring before applying power
  to the IC.
• Connect signal voltages to the circuit only
  after the IC is powered.
• Take all measurements with respect to common(
  e.g. Ground ).
• Disconnect the input signal before the dc
  power is removed. Otherwise, the IC may be
  destroyed.
• Never
• Reverse the polarity of the power
  supplies,
• Leave an input signal connected with
  no power on the IC.
