16 / 34 page  MCP6021/1R/2/3/4 DS21685C-page 16 © 2006 Microchip Technology Inc. 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 A/D CONVERTER DRIVER AND ANTI-ALIASING FILTER Figure 4-11 shows a third-order Butterworth filter that can be used as an A/D converter driver. It has a band- width 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). FIGURE 4-11: 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. 4.11.2 OPTICAL DETECTOR AMPLIFIER Figure 4-12 shows the MCP6021 op amp used as a transimpedance amplifier in a photo detector circuit. The photo detector looks like a capacitive current source, so the 100 k Ω resistor gains the input signal to a reasonable level. The 5.6 pF capacitor stabilizes this circuit and produces a flat frequency response with a bandwidth of 370 kHz.
