7 3. APPLICATION INFORMATION The MCP623 op amp is manufactured using Microchip s state-of-the-art CMOS process and is specifically designed for low-cost, low-power and general-purpose applications. The low supply voltage, low quiescent current and wide bandwidth makes the MCP623 ideal for battery-powered applications. 3. Rail-to-Rail Input The MCP623 op amp is designed to prevent phase reversal when the input pins exceed the supply voltages. Figure 3- shows the input voltage exceeding the supply voltage without any phase reversal. Input, Output Voltages (V) E+.E+ 2.E+ 3.E+ 4.E+.E+ 6.E+ 7.E+ 8.E+ 9.E+.E+ Time ( ms/div) FIGURE 3-: Phase Reversal. V OUT V IN V DD =.V G = +2 V/V The MCP623 Shows No The input stage of the MCP623 op amp uses two differential input stages in parallel. One operates at low common mode input voltage (V CM ) and the other at high V CM. With this topology, the device operates with V CM up to 3 mv above V DD and 3 mv below V SS. The Input Offset Voltage is measured at V CM =V SS 3 mv and V DD + 3 mv to ensure proper operation. Input voltages that exceed the input voltage range (V SS.3V to V DD +.3V at 2 C) can cause excessive current to flow into or out of the input pins. Current beyond ±2 ma can cause reliability problems. Applications that exceed this rating must be externally limited with a resistor, as shown in Figure 3-2. R IN MCP623 V OUT V IN + R IN FIGURE 3-2: Resistor (R IN ). ( Maximum expected V IN ) V DD ma V SS ( Minimum expected V IN ) R IN ma 3.2 Rail-to-Rail Output Input Current-Limiting The output voltage range of the MCP623 op amp is V DD 3 mv (min.) and V SS + 3 mv (max.) when R L =kω is connected to V DD /2 and V DD =.V. Refer to Figure 2-4 for more information. 3.3 Capacitive Loads Driving large capacitive loads can cause stability problems for voltage feedback op amps. As the load capacitance increases, the feedback loop s phase margin decreases and the closed-loop bandwidth is reduced. This produces gain peaking in the frequency response, with overshoot and ringing in the step response. A unity-gain buffer (G = +) is the most sensitive to capacitive loads, but all gains show the same general behavior. When driving large capacitive loads with these op amps (e.g., > pf when G = +), a small series resistor at the output (R ISO in Figure 3-3) improves the feedback loop s phase margin (stability) by making the output load resistive at higher frequencies. It does not, however, improve the bandwidth. V IN MCP623 + R ISO C L V OUT FIGURE 3-3: Output resistor, R ISO stabilizes large capacitive loads. Figure 3-4 gives recommended R ISO values for different capacitive loads and gains. The x-axis is the normalized load capacitance (C L /G N ), where G N is the circuit s noise gain. For non-inverting gains, G N and the gain are equal. For inverting gains, G N is + Gain (e.g., V/V gives G N = +2 V/V). 24 Microchip Technology Inc. DS288A-page 7

The guard ring is biased at the same voltage as the sensitive pin. An example of this type of layout is shown in Figure 3-. V IN V IN + V SS p p n n Normalized Load Capacitance; C L /G N (F) FIGURE 3-4: Recommended R ISO Values for Capactive Loads. After selecting R ISO for your circuit, double-check the resulting frequency response peaking and step response overshoot. Evaluation on the bench and simulations with the MCP623 SPICE macro model are very helpful. Modify R ISO s value until the response is reasonable. 3.4 Supply Bypass With this op amp, the power supply pin (V DD for singlesupply) should have a local bypass capacitor (i.e.,. µf to. µf) within 2 mm for good high-frequency performance. It also needs a bulk capacitor (i.e., µf or larger) within mm to provide large, slow currents. This bulk capacitor can be shared with other parts. 3. PCB Surface Leakage In applications where low input bias current is critical, PCB (printed circuit board) surface leakage effects need to be considered. Surface leakage is caused by humidity, dust or other contamination on the board. Under low humidity conditions, a typical resistance between nearby traces is 2 Ω. A V difference would cause pa, if current-to-flow. This is greater than the MCP623 family s bias current at 2 C ( pa, typ). FIGURE 3-: for Inverting Gain. Guard Ring Example Guard Ring Layout. Non-inverting Gain and Unity-Gain Buffer: a. Connect the non-inverting pin (V IN +) to the input with a wire that does not touch the PCB surface. b. Connect the guard ring to the inverting input pin (V IN ). This biases the guard ring to the common mode input voltage. 2. Inverting and transimpedance gain amplifiers (convert current to voltage, such as photo detectors): a. Connect the guard ring to the non-inverting input pin (V IN +). This biases the guard ring to the same reference voltage as the op amp (e.g., V DD /2 or ground). b. Connect the inverting pin (V IN ) to the input with a wire that does not touch the PCB surface.

9 4. APPLICATION CIRCUITS 4. Matching the impedance at the inputs To minimize the effect of input bias current in an amplifier circuit (this is important for very high sourceimpedance applications, such as ph meters and transimpedance amplifiers), the impedance at both inverting and non-inverting inputs need to be matched. This is done by choosing the circuit resistor values so that the total resistance at each input is the same. Figure 4- shows a summing amplifier circuit. R g2 4.2 Compensating for the parasitic capacitance In analog circuit design, the PCB or the development board parasitic capacitance can compromise the circuit behavior. V AC V DC R g + MCP623 - R f V OUT V IN2 V IN R x R y V DD FIGURE 4-: R g R z MCP623 + V OUT Summing Amplifier Circuit. To match the inputs, set all voltage sources to ground and calculate the total resistance at the input nodes. In this summing amplifier circuit, the resistance at the inverting input is calculated by setting V IN, V IN2 and V OUT to ground. In this case, R g, R g2 and R f are in parallel. The total resistance at the inverting input is: At the non-inverting input, V DD is the only voltage source. When V DD is set to ground, both R x and R y are in parallel. The total resistance at the non-inverting input is: To minimize output offset voltage and increase circuit accuracy, the resistor values need to meet the conditions: Rf R VIN- = R g R g2 Where: R VIN = total resistance at the inverting input R f R VIN+ = R z R x Where: R VIN+ = total resistance at the inverting input R y FIGURE 4-2: Effect of Parasitic Capacitance at the Input. For instance, Figure 4-2 shows a typical scenario. If the input of an amplifier sees parasitic capacitance of several picofarad, the frequency response of the circuit (Figure 4-3) shows that the gain-setting resistors can introduce a zero with the board parasitic capacitance. This parasitic introduces gain peaking and can cause circuit instability. One solution is to use smaller resistor values to push the zero to a higher frequency. Another solution is to compensate gain-peaking by introducing a pole at the point at which the zero occurs. This can be done by adding C f in parallel with the feedback resistor (R f ). C f needs to be selected so that the ratio C parasitic :C f is equal to the ratio of R f :R g. Figure 4-3 shows how C f enhances the frequency response of the circuit.
