If the absolute maximum input voltage is exceeded, the input current should be limited to ±5 mA maximum to prevent reducing reliability. A 10 kΩ series input resistor, used as a current limiter, will protect the input structure from voltages as large as 50V above the supply or below ground. See Figure 4-1. V DROP = 5.0V – 4.985V = 0.015V Because of output stage symmetry, the corresponding typical output low voltage (0.015V) also equals VDROP. Then: EQUATION 4-4: 0.015V = 12 R OUT = -------------------------0.001243 A VIN VOUT RIN 10kŸ FIGURE 4-1: Protection. 4.2 Input Current-Limit Output Voltage Swing Sink and source output resistances of the MIC7300 are equal. Maximum output voltage swing is determined by the load and the approximate output resistance. The output resistance is shown in Equation 4-1. 4.3 Power Dissipation The MIC7300 output drive capability requires considering power dissipation. If the load impedance is low, it is possible to damage the device by exceeding the maximum junction temperature rating. On-chip power consists of two components: supply power and output stage power. Supply power (PS) is the product of he supply voltage (VS = VV+ – VV–) and supply current (IS). Output stage power (PO) is the product of the output stage voltage drop (VDROP) and the output (load) current (IOUT). Total on-chip power dissipation is: EQUATION 4-5: EQUATION 4-1: R OUT V DROP = ----------------I LOAD VDROP is the voltage dropped within the amplifier output stage. VDROP and ILOAD can be determined from the VO (output swing) portion of the appropriate Electrical Characteristics table. ILOAD is equal to the typical output high voltage minus V+/2 and divided by RLOAD. For example, using the 5V table, the typical output high voltage using a 2 kΩ load (connected to V+/2) is 4.985V, which produces an ILOAD of: EQUATION 4-2: 4.985V – 2.5V- = 1.243mA  ----------------------------------  2k P D = PS + PO Where: PD = Total on-chip power PS = Supply power dissipation PO = Output power dissipation EQUATION 4-6: P D = V S I S + V DROP I OUT Where: VS = VV+ – VV– IS = Power supply current VDROP = VV+ – VOUT (sourcing current) VDROP = VOUT – VV– (sinking current) Equation 4-5 and 4-6 address only steady state (DC) conditions. For non-DC conditions the user must estimate power dissipation based on the RMS value of the signal. The task is one of determining the allowable on-chip power dissipation for operation at a given ambient temperature and power supply voltage. From this  2020 Microchip Technology Inc. DS20006305A-page 11 MIC7300 determination, one may calculate the maximum allowable power dissipation and, after subtracting PS, determine the maximum allowable load current, which in turn can be used to determine the minimum load impedance that may safely be driven. The calculation is summarized below. EQUATION 4-7: CFB RFB VIN VOUT T J  max  – T A P D  max  = ------------------------------ JA ΘJA(MSOP-8) = 85°C/W 4.4 Driving Capacitive Loads Driving a capacitive load introduces phase-lag into the output signal, and this in turn reduces op-amp system phase margin. The application that is least forgiving of reduced phase margin is a unity gain amplifier. The MIC7300 can typically drive a 2500 pF capacitive load connected directly to the output when configured as a unity-gain amplifier and powered with a 2.2V supply. At 10V operation the circuit typically drives 6000 pF. Phase margin is typically 40 degrees. 4.5 Using Large-Value Feedback Resistors A large-value feedback resistor (> 500 kΩ) can reduce the phase margin of a system. This occurs when the feedback resistor acts in conjunction with input capacitance to create phase lag in the feedback signal. Input capacitance is usually a combination of input circuit components and other parasitic capacitance, such as amplifier input capacitance and stray printed circuit board capacitance. Figure 4-2 illustrates a method of compensating phase lag caused by using a large-value feedback resistor. Feedback capacitor CFB introduces sufficient phase lead to overcome the phase lag caused by feedback resistor RFB and input capacitance CIN. The value of CFB is determined by first estimating CIN and then applying the following formula shown in Equation 4-8: EQUATION 4-8: R IN  C IN  R FB  C FB CIN FIGURE 4-2: Lag. 4.6 Typical Circuits Some single-supply, rail-to-rail applications for which the MIC7300 is well suited are shown in the circuit diagrams of Figure 4-3 through Figure 4-8.

All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. • Microchip is willing to work with the customer who is concerned about the integrity of their code. • Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.” Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act. Information contained in this publication regarding device applications and the like is provided only for your convenience and may be superseded by updates.
