__Short Desciption__:

Single Supply versus Dual Supply, When
op amps are powered from dual supplies (see Figure 4–1), the supplies are normally
equal in magnitude, opposing in polarity, and the center tap of the supplies is connected
to ground. Any input sources connected to ground are automatically referenced to the
center of the supply voltage, so the output voltage is automatically referenced to ground.

__Summary__:

Single-supply op amp design is more complicated than split-supply op amp design, but
with a logical design approach excellent results are achieved. Single-supply design used
to be considered technically limiting because older op amps had limited capability. The
new op amps, such as the TLC247X, TLC07X, and TLC08X have excellent single-supply
parameters; thus when used in the correct applications these op amps yield rail-to-rail
performance equal to their split-supply counterparts.

Single-supply op amp design usually involves some form of biasing, and this requires
more thought, so single-supply op amp design needs discipline and a procedure. The recommended
design procedure for single-supply op amp design is:

- Substitute the specification data into simultaneous equations to obtain m and b (the slope and intercept of a straight line).

- Let m and b determine the form of the circuit.

- Choose the circuit configuration that fits the form.

- Using the circuit equations for the circuit configuration selected, calculate the resistor values.

- Build the circuit, take data, and verify performance.

- Test the circuit for nonstandard operating conditions (circuit power off while interface power is on, over/under range inputs, etc.)

- Add protection components as required.

- Retest.

When this procedure is followed, good results follow. As single-supply circuit designers
expand their horizon, new challenges require new solutions. Remember, the only equation
a linear op amp can produce is the equation of a straight line. That equation only has
four forms. The new challenges may consist of multiple inputs, common-mode voltage
rejection, or something different, but this method can be expanded to meet these challenges.
