Analog Outputs 3.4 Chip Select Digital Input (CS) The op amp output pins are low-impedance voltage sources. This is a CMOS, Schmitt-triggered input that places the part into a low power mode of operation. 3.2 3.5 Analog Inputs The op amp non-inverting and inverting inputs are highimpedance CMOS inputs with low bias currents. 3.3 Reference Voltage (VREF, ) MCP6021 and MCP6023 Mid-supply reference voltage provided by the single op amps (except in SOT-23-5 package). This is an unbuffered, resistor voltage divider internal to the part. © 2009 Microchip Technology Inc. Power Supply (VSS and VDD) The positive power supply pin (VDD) is 2.5V to 6.0V higher than the negative power supply pin (VSS). For normal operation, the other pins are at voltages between VSS and VDD. Typically, these parts are used in a single (positive) supply configuration. In this case, VSS is connected to ground and VDD is connected to the supply. VDD will need a bypass capacitor. DS21685D-page 15 MCP6021/1R/2/3/4 NOTES: DS21685D-page 16 © 2009 Microchip Technology Inc. MCP6021/1R/2/3/4 4.0 APPLICATIONS INFORMATION VDD The MCP6021/1R/2/3/4 family of operational amplifiers are fabricated on Microchip’s state-of-the-art CMOS process. They are unity-gain stable and suitable for a wide range of general-purpose applications. 4.1 D1 V1 R1 Rail-to-Rail Input 4.1.1 R2 R3 VSS – (minimum expected V1) 2 mA VSS – (minimum expected V2) R2 > 2 mA R1 > INPUT VOLTAGE AND CURRENT LIMITS The ESD protection on the inputs can be depicted as shown in Figure 4-1. This structure was chosen to protect the input transistors, and to minimize input bias current (IB). The input ESD diodes clamp the inputs when they try to go more than one diode drop below VSS. They also clamp any voltages that go too far above VDD; their breakdown voltage is high enough to allow normal operation, and low enough to bypass quick ESD events within the specified limits. Input Stage Bond V – IN Pad VSS Bond Pad FIGURE 4-1: Structures. FIGURE 4-2: Inputs. Protecting the Analog It is also possible to connect the diodes to the left of resistors R1 and R2. In this case, current through the diodes D1 and D2 needs to be limited by some other mechanism. The resistors then serve as in-rush current limiters; the DC current into the input pins (VIN+ and VIN–) should be very small. A significant amount of current can flow out of the inputs when the common mode voltage (VCM) is below ground (VSS); see Figure 2-42. Applications that are high impedance may need to limit the useable voltage range. VDD Bond Pad VIN+ Bond Pad MCP602X V2 PHASE REVERSAL The MCP6021/1R/2/3/4 op amp is designed to prevent phase reversal when the input pins exceed the supply voltages. Figure 2-42 shows the input voltage exceeding the supply voltage without any phase reversal. 4.1.2 D2 4.1.3 NORMAL OPERATION The input stage of the MCP6021/1R/2/3/4 op amps use two differential CMOS input stages in parallel. One operates at low common mode input voltage (VCM), while the other operates at high VCM. WIth this topology, the device operates with Vcm up to 0.3V above VDD and 0.3V below VSS. Simplified Analog Input ESD In order to prevent damage and/or improper operation of these op amps, the circuit they are in must limit the currents and voltages at the VIN+ and VIN– pins (see Absolute Maximum Ratings † at the beginning of Section 1.0 “Electrical Characteristics”). Figure 4-2 shows the recommended approach to protecting these inputs. The internal ESD diodes prevent the input pins (VIN+ and VIN–) from going too far below ground, and the resistors R1 and R2 limit the possible current drawn out of the input pins. Diodes D1 and D2 prevent the input pins (VIN+ and VIN–) from going too far above VDD, and dump any currents onto VDD. When implemented as shown, resistors R1 and R2 also limit the current through D1 and D2. © 2009 Microchip Technology Inc. 4.2 Rail-to-Rail Output The Maximum Output Voltage Swing is the maximum swing possible under a particular output load. According to the specification table, the output can reach within 20 mV of either supply rail when RL = 10 kΩ. See Figure 2-31 and Figure 2-34 for more information concerning typical performance. 4.3 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. DS21685D-page 17 MCP6021/1R/2/3/4 When driving large capacitive loads with these op amps (e.g., > 60 pF when G = +1), a small series resistor at the output (RISO in Figure 4-3) improves the feedback loop’s phase margin (stability) by making the load resistive at higher frequencies. The bandwidth will be generally lower than the bandwidth with no capacitive load. VIN 1 V/V (unity gain). CG also reduces the phase margin of the feedback loop for both non-inverting and inverting gains. VIN VOUT RISO MCP602X CG VOUT RF RG CL FIGURE 4-3: Output Resistor RISO Stabilizes Large Capacitive Loads. Figure 4-4 gives recommended RISO values for different capacitive loads and gains. The x-axis is the normalized load capacitance (CL/GN), where GN is the circuit’s noise gain. For non-inverting gains, GN and the Signal Gain are equal. For inverting gains, GN is 1+|Signal Gain| (e.g., -1 V/V gives GN = +2 V/V). FIGURE 4-5: Non-inverting Gain Circuit with Parasitic Capacitance. The largest value of RF in Figure 4-5 that should be used is a function of noise gain (see GN in Section 4.3 “Capacitive Loads”) and CG. Figure 4-6 shows results for various conditions. Other compensation techniques may be used, but they tend to be more complicated to the design.

After selecting RISO for your circuit, double-check the resulting frequency response peaking and step response overshoot. Modify RISO’s value until the response is reasonable. Evaluation on the bench and simulations with the MCP6021/1R/2/3/4 Spice macro model are helpful. 4.4 GN > +1 V/V Gain Peaking Figure 2-35 and Figure 2-36 use RF = 1 kΩ to avoid (frequency response) gain peaking and (step response) overshoot. The capacitance to ground at the inverting input (CG) is the op amp’s common mode input capacitance plus board parasitic capacitance. CG is in parallel with RG, which causes an increase in gain at high frequencies for non-inverting gains greater than DS21685D-page 18 10 Noise Gain; GN (V/V) FIGURE 4-6: Non-inverting gain circuit with parasitic capacitance. 4.5 MCP6023 Chip Select (CS) The MCP6023 is a single amplifier with chip select (CS). When CS is pulled high, the supply current drops to 10 nA (typical) and flows through the CS pin to VSS. When this happens, the amplifier output is put into a high-impedance state. By pulling CS low, the amplifier is enabled. The CS pin has an internal 5 MΩ (typical) pulldown resistor connected to VSS, so it will go low if the CS pin is left floating. Figure 1-1 and Figure 2-39 show the output voltage and supply current response to a CS pulse. © 2009 Microchip Technology Inc. MCP6021/1R/2/3/4 4.6 MCP6021 and MCP6023 Reference Voltage RG VOUT VIN The single op amps (MCP6021 and MCP6023), not in the SOT-23-5 package, have an internal mid-supply reference voltage connected to the VREF pin (see Figure 4-7). The MCP6021 has CS internally tied to VSS, which always keeps the op amp on and always provides a mid-supply reference. With the MCP6023, taking the CS pin high conserves power by shutting down both the op amp and the VREF circuitry. Taking the CS pin low turns on the op amp and VREF circuitry. VREF CB FIGURE 4-9: Inverting gain circuit using VREF (MCP6021 and MCP6023 only). VDD 50 kΩ If you don’t need the mid-supply reference, leave the VREF pin open. 4.7 VREF 50 kΩ CS 5 MΩ Supply Bypass With this family of operational amplifiers, the power supply pin (VDD for single supply) should have a local bypass capacitor (i.e., 0.01 µF to 0.1 µF) within 2 mm for good, high-frequency performance. It also needs a bulk capacitor (i.e., 1 µF or larger) within 100 mm to provide large, slow currents. This bulk capacitor can be shared with nearby analog parts. 4.8 VSS (CS tied internally to VSS for MCP6021) FIGURE 4-7: Simplified internal VREF circuit (MCP6021 and MCP6023 only). See Figure 4-8 for a non-inverting gain circuit using the internal mid-supply reference. The DC-blocking capacitor (CB) also reduces noise by coupling the op amp input to the source. RG RF RF Unused Op Amps An unused op amp in a quad package (MCP6024) should be configured as shown in Figure 4-10. 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. ¼ MCP6024 (A) ¼ MCP6024 (B) VDD VOUT CB VREF R1 VDD VDD VIN FIGURE 4-8: Non-inverting gain circuit using VREF (MCP6021 and MCP6023 only).

DS21685D-page 19 MCP6021/1R/2/3/4 4.9 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 1012Ω. A 5V difference would cause 5 pA of current to flow, which is greater than the MCP6021/1R/2/3/4 family’s bias current at +25°C (1 pA, typical). The easiest way to reduce surface leakage is to use a guard ring around sensitive pins (or traces). The guard ring is biased at the same voltage as the sensitive pin. Figure 4-11 shows an example of this type of layout. Guard Ring VIN– VIN+ Separate digital from analog, low speed from high speed and low power from high power. This will reduce interference. Keep sensitive traces short and straight. Separating them from interfering components and traces. This is especially important for high-frequency (low rise-time) signals. Sometimes it helps to place guard traces next to victim traces. They should be on both sides of the victim trace, and as close as possible. Connect the guard trace to ground plane at both ends, and in the middle for long traces. Use coax cables (or low inductance wiring) to route signal and power to and from the PCB. 4.11 Typical Applications 4.11.1 FIGURE 4-11: Layout. 1. 2. Example Guard Ring Non-inverting Gain and Unity-Gain Buffer. a) Connect the guard ring to the inverting input pin (VIN–); this biases the guard ring to the common mode input voltage. b) Connect the non-inverting pin (VIN+) to the input with a wire that does not touch the PCB surface. Inverting (Figure 4-11) and Transimpedance Gain Amplifiers (convert current to voltage, such as photo detectors). a) Connect the guard ring to the non-inverting input pin (VIN+). This biases the guard ring to the same reference voltage as the op amp’s input (e.g., VDD/2 or ground). b) Connect the inverting pin (VIN–) to the input with a wire that does not touch the PCB surface. 4.10 A/D CONVERTER DRIVER AND ANTI-ALIASING FILTER Figure 4-12 shows a third-order Butterworth filter that can be used as an A/D converter driver. It has a bandwidth of 20 kHz and a reasonable step response. It will work well for conversion rates of 80 ksps and greater (it has 29 dB attenuation at 60 kHz). 1.0 nF 8.45 kΩ 14.7 kΩ 33.2 kΩ 1.2 nF 100 pF MCP602X FIGURE 4-12: A/D Converter Driver and Anti-aliasing Filter with a 20 kHz Cutoff Frequency. This filter can easily be adjusted to another bandwidth by multiplying all capacitors by the same factor. Alternatively, the resistors can all be scaled by another common factor to adjust the bandwidth. High Speed PCB Layout Due to their speed capabilities, a little extra care in the PCB (Printed Circuit Board) layout can make a significant difference in the performance of these op amps. Good PC board layout techniques will help you achieve the performance shown in Section 1.0 “Electrical Characteristics” and Section 2.0 “Typical Performance Curves”, while also helping you minimize EMC (Electro-Magnetic Compatibility) issues. Use a solid ground plane and connect the bypass local capacitor(s) to this plane with minimal length traces. This cuts down inductive and capacitive crosstalk.
