input stage MCP6291/2/3/4/5 amps differential CMOS input stages parallel. operates common mode input voltage (VCM), while other operates high VCM. With this topology, device operates with above below VSS. Input Offset Voltage (VOS) measured ensure proper operation. Input voltages that exceed absolute maximum voltage (VSS 0.3V 0.3V) cause excessive current flow into input pins. Current beyond cause reliability problems. Applications that exceed this rating must externally limited with resistor, shown Figure 4-2.
Driving large capacitive loads cause stability problems voltage feedback amps. load capacitance increases, feedback loop's phase margin decreases closed-loop bandwidth reduced. This produces gain peaking frequency response, with overshoot ringing step response. unity-gain buffer most sensitive capacitive loads, though gains show same general behavior. When driving large capacitive loads with these amps (e.g., when +1), small series resistor output (RISO Figure 4-3) improves feedback loop's phase margin (stability) making output load resistive higher frequencies. bandwidth will generally lower than bandwidth with capacitive load.

This model intended initial design tool that works well amp's linear region operation room temperature. macro model file information capabilities. Bench testing very important part design cannot replaced with simulations. Also, simulation results using this macro model need validated comparing them data sheet specifications characteristic curves.
FilterLab® Software
FIGURE 4-16: Capacitorless Second-Order Low-Pass Filter with Chip Select.
Microchip's FilterLab software innovative tool that simplifies analog active-filter (using amps) design. Available cost from site www.microchip.com, FilterLab design tool provides full schematic diagrams filter circuit with component values. also outputs filter circuit SPICE format, which used with macro model simulate actual filter performance.
