It is used to place the MCP608 op amp in a Low-power mode, with the output(s) in a Hi-Z state. © 2009 Microchip Technology Inc. 3.4 Negative Power Supply Power Supply Pins The positive power supply pin (VDD) is 2.5V to 5.5V higher than the negative power supply pin (VSS). For normal operation, the output pins are at voltages between VSS and VDD; while the input pins are at voltages between VSS – 0.3V and VDD + 0.3V. Typically, these parts are used in a single-supply (positive) configuration. In this case, VSS is connected to ground and VDD is connected to the supply. VDD will need bypass capacitors .

MCP606/7/8/9 4.0 APPLICATIONS INFORMATION VDD The MCP606/7/8/9 family of op amps is manufactured using Microchip’s state-of-the-art CMOS process These op amps are unity-gain stable and suitable for a wide range of general purpose applications. 4.1 D1 V1 R1 Rail-to-Rail Inputs 4.1.1 PHASE REVERSAL R2 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.

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. 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 2-31. Applications that are high impedance may need to limit the useable voltage range. 4.1.3 VIN+ Bond Pad MCP60X V2 The MCP606/7/8/9 op amp is designed to prevent phase reversal when the input pins exceed the supply voltages. Figure 2-23 shows the input voltage exceeding the supply voltage without any phase reversal. 4.1.2 D2 NORMAL OPERATION The input stage of the MCP606/7/8/9 op amps use a PMOS input stage. It operates at low common mode input voltage (VCM), including ground. WIth this topology, the device operates with VCM up to VDD –1.1V and 0.3V below VSS. Figure 4-3 shows a unity gain buffer. Since VOUT is the same voltage as the inverting input, VOUT must be kept below VDD–1.2V for correct operation. VIN + MCP60X – VOUT FIGURE 4-3: Unity Gain Buffer has a Limited VOUT Range. DS11177F-page 15 MCP606/7/8/9 4.2 Rail-to-Rail Output 10k The second specification that describes the outputswing capability of these amplifiers (Linear Output Voltage Range) defines the maximum output swing that can be achieved while the amplifier still operates in its linear region. To verify linear operation in this range, the large-signal DC Open-Loop Gain (AOL) is measured at points inside the supply rails. The measurement must meet the specified AOL conditions in the specification table. 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. A unity-gain buffer (G = +1) is the most sensitive to capacitive loads, though all gains show the same general behavior. 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 4-4) improves the feedback loop’s phase margin (stability) by making the output load resistive at higher frequencies. The bandwidth will be generally lower than the bandwidth with no capacitive load. RISO MCP60X VIN Recommended R ISO (Ω) 10000 There are two specifications that describe the output-swing capability of the MCP606/7/8/9 family of op amps. The first specification (Maximum Output Voltage Swing) defines the absolute maximum swing that can be achieved under the specified load conditions. For instance, the output voltage swings to within 15 mV of the negative rail with a 25 kΩ load to VDD/2. Figure 2-23 shows how the output voltage is limited when the input goes beyond the linear region of operation. 1k 1000 GN = +1 GN = +2 GN ≥ +4 100 10p 100 10 100 1000 10000 100p 1n 10n Normalized Load Capacitance; CL/GN (F) FIGURE 4-5: Recommended RISO Values for Capacitive Loads. 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 MCP606/7/8/9 SPICE macro model are helpful. 4.4 MCP608 Chip Select The MCP608 is a single op amp with Chip Select (CS). When CS is pulled high, the supply current drops to 50 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) pull-down resistor connected to VSS, so it will go low if the CS pins is left floating. Figure 1-1 shows the output voltage and supply current response to a CS pulse. 4.5 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 other nearby analog parts. VOUT CL FIGURE 4-4: Output Resistor, RISO stabilizes large capacitive loads. Figure 4-5 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). DS11177F-page 16 © 2009 Microchip Technology Inc. MCP606/7/8/9 4.6 Unused Op Amps 1. An unused op amp in a quad package (MCP609) should be configured as shown in Figure 4-6. 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. 2. ¼ MCP609 (B) ¼ MCP609 (A) VDD VDD VDD R1 4.8 VREF R2 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 Transimpedance Gain (convert current to voltage, such as photo detectors) amplifiers: 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. Application Circuits 4.8.1 R2 V REF = V DD ⋅ ------------------R1 + R2 FIGURE 4-6: 4.7 Unused Op Amps. PCB Surface Leakage In applications where low input bias current is critical, Printed Circuit Board (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 1012Ω. A 5V difference would cause 5 pA of current to flow, which is greater than the MCP606/7/8/9 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. An example of this type of layout is shown in Figure 4-7. VIN- VIN+ LOW-SIDE BATTERY CURRENT SENSOR The MCP606/7/8/9 op amps can be used to sense the load current on the low-side of a battery using the circuit in Figure 4-8. In this circuit, the current from the power supply (minus the current required to power the MCP606) flows through a sense resistor (RSEN), which converts it to voltage. This is gained by the the amplifier and resistors, RG and RF . Since the non-inverting input of the amplifier is at the load’s negative supply (VLM), the gain from RSEN to VOUT is RF/RG .

( RF ⁄ RG ) IL FIGURE 4-8: Sensor. FIGURE 4-7: for Inverting Gain. SEN Low Side Battery Current Since the input bias current and input offset voltage of the MCP606 are low, and the input is capable of swinging below ground, there is very little error generated by the amplifier. The quiescent current is very low, which helps conserve battery power. The rail-to-rail output makes it possible to read very low currents. DS11177F-page 17 MCP606/7/8/9 4.8.2 PHOTODIODE AMPLIFIERS Sensors that produce an output current and have high output impedance can be connected to a transimpedance amplifier. The transimpedance amplifier converts the current into voltage. Photodiodes are one sensor that produce an output current. The key op amp characteristics that are needed for these circuits are: low input offset voltage, low input bias current, high input impedance and an input common mode range that includes ground. The low input offset voltage and low input bias current support a very low voltage drop across the photodiode; this gives the best photodiode linearity. Since the photodiode is biased at ground, the op amp’s input needs to function well both above and below ground. 4.8.2.1 operate at a much higher speed. This reverse bias also increases the dark current and current noise, however. Resistor R2 converts the current into voltage. Capacitor C2 limits the bandwidth and helps stabilize the circuit when D1’s junction capacitance is large.

As light impinges on D1, charge is generated, causing a current to flow in the reverse bias direction of D1. The op amp’s negative feedback forces the voltage across the D1 to be nearly 0V. Resistor R2 converts the current into voltage. Capacitor C2 limits the bandwidth and helps stabilize the circuit when D1’s junction capacitance is large.

This configuration is best suited for higher gains (i.e., gain > 3 V/V). The reference voltage (VREF) is typically at mid-supply (VDD/2) in a single-supply environment.

As light impinges on D1, charge is generated, causing a current to flow in the reverse bias direction of D1. Placing a negative bias on D1 significantly reduces its junction capacitance, which allows the circuit to DS11177F-page 18 V2 VOUT ½ MCP607 ½ MCP607 V1 FIGURE 4-11: Two Op Amp Instrumentation Amplifier.

MCP606/7/8/9 4.8.4 THREE OP AMP INSTRUMENTATION AMPLIFIER 4.8.5 PRECISION GAIN WITH GOOD LOAD ISOLATION A classic, three op amp instrumentation amplifier is illustrated in Figure 4-12. The two input op amps provide differential signal gain and a common mode gain of +1. The output op amp is a difference amplifier, which converts its input signal from differential to a single ended output; it rejects common mode signals at its input. The gain of this circuit is simply adjusted with one resistor (RG). The reference voltage (VREF) is typically referenced to mid-supply (VDD/2) in single-supply applications. In Figure 4-13, the MCP606 op amps, R1 and R2 provide a high gain to the input signal (VIN). The MCP606’s low offset voltage makes this an accurate circuit. 2R ⎞ ⎛ R 4⎞ ⎛ VOUT = ( V 1 – V 2 ) ⎜1 + ---------2 ⎟ ⎜ ------⎟ + V REF R G ⎠ ⎝ R 3⎠ ⎝ VOUT = V IN (1 + R 2 ⁄ R 1 ) V2 ½ MCP607 The MCP601 is configured as a unity-gain buffer. It isolates the MCP606’s output from the load, increasing the high-gain stage’s precision. Since the MCP601 has a higher output current, with the two amplifiers being housed in separate packages, there is minimal change in the MCP606’s offset voltage due to loading effect.

Note the following details of the code protection feature on Microchip devices: • Microchip products meet the specification contained in their particular Microchip Data Sheet. • Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. • There are dishonest and possibly illegal methods used to breach the code protection feature. 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.
