Calculating DC Offset.
To calculate the DC bias point and DC offset, convert
the circuit to its DC equivalent:
• Replace capacitors with open circuits
• Replace inductors with short circuits
• Replace AC voltage sources with short circuits
• Replace AC current sources with open circuits
• Convert DC sources and resistances into their

There are two specifications that describe the output
swing capability of the MCP616/7/8/9 family of op
amps. The first specification (Maximum Output Voltage
Swing) defines the absolute maximum swing that can
be achieved under the specified load conditions. For
instance, the output voltage swings to within 15 mV of
the negative rail with a 25 kΩ load tied to V
Figure 2-33
when the input goes beyond the linear region of
operation.
The second specification that describes the output
swing capability of these amplifiers is the Linear Output
Voltage
maximum output swing that can be achieved while the
amplifier still operates in its linear region. To verify
linear operation in this range, the large-signal DC
