MCP606/7/8/9 4.0 APPLICATIONS INFORMATION VDD The MCP606/7/8/9 family of op amps is manufactured using Microchip’s state-of-the-art CMOS process These op amps are unity-gain stable and suitable for a wide range of general purpose applications. 4.1 D1 V1 R1 Rail-to-Rail Inputs 4.1.1 PHASE REVERSAL R2 INPUT VOLTAGE AND CURRENT LIMITS The ESD protection on the inputs can be depicted as shown in Figure 4-1.
MCP606/7/8/9 4.2 Rail-to-Rail Output 10k The second specification that describes the outputswing capability of these amplifiers (Linear Output Voltage Range) defines the 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 Open-Loop Gain (AOL) is measured at points inside the supply rails. The measurement must meet the specified AOL conditions in the specification table. 4.
MCP606/7/8/9 4.6 Unused Op Amps 1. An unused op amp in a quad package (MCP609) should be configured as shown in Figure 4-6. These circuits prevent the output from toggling and causing crosstalk. Circuits A sets the op amp at its minimum noise gain. The resistor divider produces any desired reference voltage within the output voltage range of the op amp; the op amp buffers that reference voltage. Circuit B uses the minimum number of components and operates as a comparator, but it may draw more current.
MCP606/7/8/9 4.8.2 PHOTODIODE AMPLIFIERS Sensors that produce an output current and have high output impedance can be connected to a transimpedance amplifier. The transimpedance amplifier converts the current into voltage. Photodiodes are one sensor that produce an output current. The key op amp characteristics that are needed for these circuits are: low input offset voltage, low input bias current, high input impedance and an input common mode range that includes ground.
MCP606/7/8/9 4.8.4 THREE OP AMP INSTRUMENTATION AMPLIFIER 4.8.5 PRECISION GAIN WITH GOOD LOAD ISOLATION A classic, three op amp instrumentation amplifier is illustrated in Figure 4-12. The two input op amps provide differential signal gain and a common mode gain of +1. The output op amp is a difference amplifier, which converts its input signal from differential to a single ended output; it rejects common mode signals at its input. The gain of this circuit is simply adjusted with one resistor (RG).
