Analog Outputs The output pins are low-impedance voltage sources. 3.2 Description Analog Inputs The non-inverting and inverting inputs are high-impedance CMOS inputs with low bias currents. 3.3 Power Supply Pins The positive power supply (VDD) is 3.5V to 16V higher than the negative power supply (VSS). For normal operation, the other pins are at voltages between VSS and VDD. Typically, these parts can be used in single-supply operation or dual-supply operation. Also, VDD will need bypass capacitors. 3.4 Exposed Thermal Pad (EP) There is an internal electrical connection between the Exposed Thermal Pad (EP) and the VSS pin; they must be connected to the same potential on the Printed Circuit Board (PCB). 2010-2011 Microchip Technology Inc.

MCP6H01/2/4 4.0 APPLICATION INFORMATION The MCP6H01/2/4 family of op amps is manufactured using Microchip’s state-of-the-art CMOS process and is specifically designed for low-power, high-precision applications. 4.1 VDD D1 D2 V1 Inputs 4.1.1 MCP6H0X V2 PHASE REVERSAL The MCP6H01/2/4 op amps are designed to prevent phase reversal when the input pins exceed the supply voltages. Figure 2-36 shows the input voltage exceeding the supply voltage without any phase reversal. 4.1.2 INPUT VOLTAGE LIMITS In order to prevent damage and/or improper operation of these amplifiers, the circuit must limit the voltages at the input pins (see Section 1.1 “Absolute Maximum Ratings †”). The ESD protection on the inputs can be depicted as shown in Figure 4-1. This structure was chosen to protect the input transistors against many (but not all) over-voltage conditions, and to minimize the input bias current (IB). FIGURE 4-2: Inputs. Protecting the Analog A significant amount of current can flow out of the inputs when the common mode voltage (VCM) is below ground (VSS), see Figure 2-38. 4.1.3 INPUT CURRENT LIMITS In order to prevent damage and/or improper operation of these amplifiers, the circuit must limit the currents into the input pins (see Section 1.1 “Absolute Maximum Ratings †”). Figure 4-3 shows one approach to protecting these inputs. The resistors R1 and R2 limit the possible currents in or out of the input pins (and the ESD diodes, D1 and D2). The diode currents will go through either VDD or VSS. VDD Bond Pad VDD D1 Bond VIN+ Pad VOUT Input Stage Bond VIN– Pad D2 V1 R1 MCP6H0X VOUT V2 R2 VSS Bond Pad FIGURE 4-1: Structures. R3 Simplified Analog Input ESD 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 well above VDD. Their breakdown voltage is high enough to allow normal operation, but not low enough to protect against slow overvoltage (beyond VDD) events. Very fast ESD events (that meet the specification) are limited so that damage does not occur. In some applications, it may be necessary to prevent excessive voltages from reaching the op amp inputs; Figure 4-2 shows one approach to protecting these inputs. 2010-2011 Microchip Technology Inc. VSS – (minimum expected V1) 2 mA VSS – (minimum expected V2) R2 > 2 mA R1 > FIGURE 4-3: Inputs. 4.1.4 Protecting the Analog NORMAL OPERATION The inputs of the MCP6H01/2/4 op amps connect to a differential PMOS input stage. It operates at a low common mode input voltage (VCM), including ground. With this topology, the device operates with a VCM up to VDD – 2.3V and 0.3V below VSS (refer to Figure 2-3 through 2-5). The input offset voltage is measured at VCM = VSS – 0.3V and VDD – 2.3V to ensure proper operation. DS22243D-page 17 MCP6H01/2/4 For a unity gain buffer, VIN must be maintained below VDD – 2.3V for correct operation. Rail-to-Rail Output The output voltage range of the MCP6H01/2/4 op amps is 0.020V (typical) and 14.980V (typical) when RL = 10 k is connected to VDD/2 and VDD = 15V. Refer to Figures 2-24 through 2-29 for more information. 4.3 When driving large capacitive loads with these op amps (e.g., > 100 pF when G = + 1V/V), a small series resistor at the output (RISO in Figure 4-4) improves the feedback loop’s phase margin (stability) by making the output load resistive at higher frequencies. The bandwidth will generally be lower than the bandwidth with no capacitance load. – MCP6H0X + RISO VOUT CL FIGURE 4-4: Output Resistor, RISO Stabilizes Large Capacitive Loads. Figure 4-5 gives the 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., -1V/V gives GN = +2V/V). 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. Bench evaluation and simulations with the MCP6H01/2/4 SPICE macro model are helpful. VDD = 16V RL = 10 kΩ 100 GN: 1 V/V 2 V/V 5 V/V 10 1 10p 100p 1n 10n 0.1µ 1.E-06 1µ 1.E-11 1.E-10 1.E-09 1.E-08 1.E-07 Normalized Load Capacitance; CL/GN (F) 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. While a unity-gain buffer (G = +1V/V) is the most sensitive to capacitive loads, all gains show the same general behavior. VIN Recommended R ISO (Ω) 4.2 1000 1k FIGURE 4-5: Recommended RISO Values for Capacitive Loads. 4.4 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 can use a bulk capacitor (i.e., 1 µF or larger) within 100 mm to provide large, slow currents. This bulk capacitor can be shared with other analog parts. 4.5 Unused Op Amps An unused op amp in a quad package (MCP6H04) should be configured as shown in Figure 4-6. These circuits prevent the output from toggling and causing crosstalk. Circuit 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, and 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 MCP6H04 (A) VDD R1 VDD VDD R2 VREF R2 V REF = VDD -------------------R1 + R2 FIGURE 4-6: DS22243D-page 18 ¼ MCP6H04 (B) Unused Op Amps. 2010-2011 Microchip Technology Inc. MCP6H01/2/4 4.6 PCB Surface Leakage 4.7 In applications where low input bias current is critical, PCB 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 1012. A 15V difference would cause 15 pA of current to flow; which is greater than the MCP6H01/2/4 family’s bias current at +25°C (10 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. An example of this type of layout is shown in Figure 4-7. Guard Ring VIN– VIN+ VSS 4.7.1 Application Circuits DIFFERENCE AMPLIFIER The MCP6H01/2/4 op amps can be used in current sensing applications. Figure 4-8 shows a resistor (RSEN) that converts the sensor current (ISEN) to voltage, as well as a difference amplifier that amplifies the voltage across the resistor while rejecting common mode noise. R1 and R2 must be well matched to obtain an acceptable Common Mode Rejection Ratio (CMRR). Moreover, RSEN should be much smaller than R1 and R2 in order to minimize the resistive loading of the source. To ensure proper operation, the op amp common mode input voltage must be kept within the allowed range. The reference voltage (VREF) is supplied by a low-impedance source. In single-supply applications, VREF is typically VDD/2. . R1 R2 VREF VDD FIGURE 4-7: for Inverting Gain. 1. 2. Example Guard Ring Layout Non-inverting Gain and Unity-Gain Buffer: a. Connect the non-inverting pin (VIN+) to the input with a wire that does not touch the PCB surface. b. Connect the guard ring to the inverting input pin (VIN–). This biases the guard ring to the common mode input voltage. Inverting Gain and Trans-impedance 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 (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. 2010-2011 Microchip Technology Inc.

DS22243D-page 19 MCP6H01/2/4 4.7.2 TWO OP AMP INSTRUMENTATION AMPLIFIER The MCP6H01/2/4 op amps are well suited for conditioning sensor signals in battery-powered applications. Figure 4-9 shows a two op amp instrumentation amplifier using the MCP6H02, which works well for applications requiring rejection of common mode noise at higher gains. To ensure proper operation, the op amp common mode input voltage must be kept within the allowed range. The reference voltage (VREF) is supplied by a lowimpedance source. In single-supply applications, VREF is typically VDD/2. RG VREF R1 R2 R2 4.7.3 PHOTODETECTOR AMPLIFIER The MCP6H01/2/4 op amps can be used to easily convert the signal from a sensor that produces an output current (such as a photo diode) into voltage (a trans-impedance amplifier). This is implemented with a single resistor (R2) in the feedback loop of the amplifiers shown in Figure 4-10. The optional capacitor (C2) sometimes provides stability for these circuits. A photodiode configured in Photovoltaic mode has a zero voltage potential placed across it. In this mode, the light sensitivity and linearity is maximized, making it best suited for precision applications. The key amplifier specifications for this application are: low input bias current, common mode input voltage range (including ground), and rail-to-rail output.

MCP6H01/2/4 5.0 DESIGN AIDS Microchip provides the basic design tools needed for the MCP6H01/2/4 family of op amps. 5.1 SPICE Macro Model The latest SPICE macro model for the MCP6H01/2/4 op amp is available on the Microchip web site at www.microchip.com. The model was written and tested in PSPICE owned by Orcad (Cadence). For other simulators, it may require translation. The model covers a wide aspect of the op amp’s electrical specifications. Not only does the model cover voltage, current and resistance of the op amp, but it also covers the temperature and noise effects on the behavior of the op amp. The model has not been verified outside the specification range listed in the op amp data sheet. The model behaviors under these conditions cannot be guaranteed to match the actual op amp performance. Moreover, the model is intended to be an initial design tool. Bench testing is a very important part of any design and cannot be replaced with simulations. Also, simulation results using this macro model need to be validated by comparing them to the data sheet specifications and characteristic curves. 5.2 FilterLab Software Microchip’s FilterLab software is an innovative software tool that simplifies analog active filter (using op amps) design. Available at no cost from the Microchip web site at www.microchip.com/filterlab, the FilterLab design tool provides full schematic diagrams of the filter circuit with component values. It also outputs the filter circuit in SPICE format, which can be used with the macro model to simulate actual filter performance. 5.3 MAPS (Microchip Advanced Part Selector) MAPS is a software tool that helps semiconductor professionals efficiently identify Microchip devices that fit a particular design requirement. Available at no cost from the Microchip web site at www.microchip.com/ maps, MAPS is an overall selection tool for Microchip’s product portfolio that includes analog, memory, MCUs and DSCs. Using this tool, you can define a filter to sort features for a parametric search of devices and export side-by-side technical comparison reports.
