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 3-1. VOUT RIN VIN 10kΩ FIGURE 3-1: Protection. 3.2 Input Current-Limit Output Voltage Swing Sink and source output resistances of the MIC7122 are equal. Maximum output voltage swing is determined by the load and the approximate output resistance. The output resistance is: EQUATION 3-1: V DROP R OUT = ----------------I LOAD Because of output stage symmetry, the corresponding typical output low voltage (13 mV) also equals VDROP. Then: EQUATION 3-3: 0.013V R OUT = -------------------------- = 10.5 0.001244 A 3.3 Power Dissipation The MIC7122 output drive capability requires considering power dissipation. If the load impedance is low, it is possible to damage the device by exceeding the 125°C junction temperature rating. On-chip power consists of two components: supply power and output stage power. Supply power (PS) is the product of the 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 3-4: P D = PS + PO Where: PD = Total On-Chip Power PS = Supply Power Dissipation PO = Output Power Dissipation EQUATION 3-5: 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 DC Electrical Characteristics (5V) table, the typical output high voltage drops 13 mV using a 2 kΩ load (connected to V+/2), which produces an ILOAD of: EQUATION 3-2: 5.0V – 0.013V – 2.5V ------------------------------------------------------ = 1.244mA 2k  2020 Microchip Technology Inc. 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 3-4 and Equation 3-5 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 determination, one may calculate the maximum allowable power dissipation and, after subtracting PS, determine the maximum allowable load current, which DS20006290A-page 11 MIC7122 in turn can be used to determine the minimum load impedance that may safely be driven. The calculation is summarized below in Equation 3-6. CFB RFB EQUATION 3-6: RIN VIN VOUT T J  MAX  – T A P D  MAX  = --------------------------------- JA CIN FIGURE 3-2: Lag. 3.4 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 MIC7122 can typically drive a 200 pF capacitive load connected directly to the output when configured as a unity-gain amplifier and powered with a 2.2V supply. At 15V operation the circuit typically drives 500 pF. 3.5 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 3-2 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: Because a significant percentage of CIN may be caused by board layout, it is important to note that the correct value of CFB may change when changing from a breadboard to the final circuit layout. 3.6 Typical Circuits Some single-supply, rail-to-rail applications for which the MIC7122 is well suited are shown in the circuit diagrams of Figure 3-3 through Figure 3-8.
