*
* Macromodel for the MCP6001/2/4 op amp family:
* MCP6001, MCP6001R, MCP6001U, MCP6002, MCP6004
*
* Revision History:
* REV A: 21-Jun-02, Created model
* REV B: 16-Jul-02, Improved output stage
* REV C: 03-Jan-03, Added MCP6001
* REV D: 19-Aug-06, Added over temperature, improved output stage,
* fixed overdrive recovery time
* REV E: 27-Jul-07, Updated output impedance for better model stability w/cap load
* REV F: 09-Jul-12, Added MCP6001R, MCP6001U
*
* Recommendations:
* Use PSPICE (other simulators may require translation)
* For a quick, effective design, use a combination of: data sheet
* specs, bench testing, and simulations with this macromodel
* For high impedance circuits, set GMIN=100F in .OPTIONS
*
* Supported:
* Typical performance for temperature range (-40 to 125) degrees Celsius
* DC, AC, Transient, and Noise analyses.
* Most specs, including: offsets, DC PSRR, DC CMRR, input impedance,
* open loop gain, voltage ranges, supply current, ... , etc.
* Temperature effects for Ibias, Iquiescent, Iout short circuit
* current, Vsat on both rails, Slew Rate vs. Temp and P.S.
*
* Not Supported:
* Some Variation in specs vs. Power Supply Voltage
* Monte Carlo (Vos, Ib), Process variation
* Distortion (detailed non-linear behavior)
* Behavior outside normal operating region
*
* Input Stage
