This equation holds when there are no gain or offset errors and when the VREF pin is tied to a low impedance source ( VPOR). A 0.1 µF bypass capacitor mounted as close as possible to the VDD pin provides additional transient immunity. DS21117B-page 24  2003-2012 Microchip Technology Inc. MCP6S21/2/6/8 6.0 APPLICATIONS INFORMATION 6.1 Changing External Reference Voltage Figure 6-1 shows a MCP6S21 with the VREF pin at 2.5V and VDD = 5.0V. This allows the PGA to amplify signals centered on 2.5V, instead of ground-referenced signals. The voltage reference MCP1525 is buffered by a MCP6021, which gives a low output impedance reference voltage from DC to high frequencies. The source driving the VREF pin should have an output impedance of  0.1 to maintain reasonable gain accuracy. VDD VDD VIN MCP1525 VDD VOUT MCP6S21 VREF For CL  100 pF, a good estimate for RISO is 50. This value can be fine-tuned on the bench. Adjust RISO so that the step response overshoot and frequency response peaking are acceptable at all gains. 6.3 Layout Considerations Good PC board layout techniques will help achieve the performance shown in the Electrical Characteristics and Typical Performance Curves. It will also help minimize EMC (Electro-Magnetic Compatibility) issues. 6.3.1 COMPONENT PLACEMENT Separate circuit functions; digital from analog, low speed from high speed, and low power from high power, as this will reduce crosstalk. Keep sensitive traces short and straight, separating them from interfering components and traces. This is especially important for high frequency (low rise time) signals. Use a 0.1 µF supply bypass capacitor within 0.1 inch (2.5 mm) of the VDD pin. It must connect directly to the ground plane. A multi-layer ceramic chip capacitor, or high-frequency equivalent, works best. 2.5V REF MCP6021 6.3.2 1 µF FIGURE 6-1: PGA with Different External Reference Voltage. 6.2 Capacitive Load and Stability Large capacitive loads can cause both stability problems and reduced bandwidth for the MCP6S21/2/6/8 family of PGAs (Figure 2-17 and Figure 2-18). This happens because a large load capacitance decreases the internal amplifier’s phase margin and bandwidth. If the PGA drives a large capacitive load, the circuit in Figure 6-2 can be used. A small series resistor (RISO) at the VOUT improves the phase margin by making the load resistive at high frequencies. It will not, however, improve the bandwidth. The input pins of the MCP6S21/2/6/8 family of operational amplifiers (op amps) are high-impedance. This makes them especially susceptible to capacitively-coupled noise. Using a ground plane helps reduce this problem. When noise is capacitively-coupled, the ground plane provides additional shunt capacitance to ground. When noise is magnetically coupled, the ground plane reduces the mutual inductance between traces. Increasing the separation between traces makes a significant difference. Changing the direction of one of the traces can also reduce magnetic coupling. It may help to locate guard traces next to the victim trace. They should be on both sides of the victim trace and be as close as possible. Connect the guard traces to the ground plane at both ends, and in the middle, of long traces. 6.3.3 RISO VIN MCP6S2X VOUT CL FIGURE 6-2: Capacitive Loads. PGA Circuit for Large  2003-2012 Microchip Technology Inc. SIGNAL COUPLING HIGH FREQUENCY ISSUES Because the MCP6S21/2/6/8 PGAs reach unity gain near 64 MHz when G = 16 and 32, it is important to use good PCB layout techniques. Any parasitic coupling at high frequency might cause undesired peaking. Filtering high frequency signals (i.e., fast edge rates) can help. To minimize high frequency problems: • • • • • Use complete ground and power planes Use HF, surface mount components Provide clean supply voltages and bypassing Keep traces short and straight Try a linear power supply (e.g., an LDO) DS21117B-page 25 MCP6S21/2/6/8 6.4 Typical Applications 6.4.1 VIN  GAIN RANGING MCP6021 Figure 6-3 shows a circuit that measures the current IX. It benefits from changing the gain on the PGA. Just as a hand-held multimeter uses different measurement ranges to obtain the best results, this circuit makes it easy to set a high gain for small signals and a low gain for large signals. As a result, the required dynamic range at the PGA’s output is less than at its input (by up to 30 dB).  10.0 k VOUT MCP6S21 1.11 k FIGURE 6-5: MCP6S2X IX 6.4.3 VOUT FIGURE 6-3: Wide Dynamic Range Current Measurement Circuit. SHIFTED GAIN RANGE PGA Figure 6-4 shows a circuit using an MCP6021 at a gain of +10 in front of an MCP6S21. This changes the overall gain range to +10 V/V to +320 V/V (from +1 V/V to +32 V/V). VIN EXTENDED GAIN RANGE PGA Figure 6-6 gives a +1 V/V to +1024 V/V gain range, which is much greater than the range for a single PGA (+1 V/V to +32 V/V). The first PGA provides input multiplexing capability, while the second PGA only needs one input. These devices can be daisy chained (Section 5.3, “Daisy Chain Configuration”). RS 6.4.2 PGA with lower gain range. MCP6S21 VOUT  PGA with Modified Gain It is also easy to shift the gain range to lower gains (see Figure 6-6). The MCP6021 acts as a unity gain buffer, and the resistive voltage divider shifts the gain range down to +0.1 V/V to +3.2 V/V (from +1 V/V to +32 V/V). DS21117B-page 26 6.4.4 MCP6S21 VOUT PGA with Extended Gain MULTIPLE SENSOR AMPLIFIER The multiple channel PGAs (except the MCP6S21) allow the user to select which sensor appears on the output (see Figure 6-7). These devices can also change the gain to optimize performance for each sensor. 10.0 k 1.11 k FIGURE 6-4: Range.

Obviously, Sensors #7-14 have a high total gain range available, as explained in Section 6.4.3, “Extended Gain Range”. These devices can be daisy chained (Section 5.3, “Daisy Chain Configuration”). ADC DRIVER The family of PGA’s is well suited for driving Analog-toDigital Converters (ADC). The binary gains (1, 2, 4, 8, 16 and 32) effectively add five more bits to the input range (see Figure 6-10). This works well for applications needing relative accuracy more than absolute accuracy (e.g., power monitoring).

PIC MCU WITH EXPANDED INPUT CAPABILITY Figure 6-9 shows an MCP6S28 driving an analog input to a PIC microcontroller. This greatly expands the input capacity of the microcontroller, while adding the ability to select the appropriate gain for each source. VIN OUT MCP6S28 FIGURE 6-10: 6.4.6 MCP3201 MCP6S28 PGA as an ADC Driver. At low gains, the ADC’s Signal-to-Noise Ratio (SNR) will dominate since the PGAs input noise voltage density is so low (10 nV/Hz @ 10 kHz, typ.). At high gains, the PGA’s noise will dominate the SNR, but its low noise supports most applications. Again, these PGAs add the flexibility of selecting the best gain for an application. The low pass filter in the block diagram reduces the integrated noise at the MCP6S28’s output and serves as an anti-aliasing filter.

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.
