• Active Filtering General Description The MIC6211 op amp is a general-purpose, high performance, single- or split-supply, operational amplifier in a space-saving, surface-mount package. The MIC6211 operates from 4V to 32V, single or dif ferential (split) supply. The input common-mode range includes ground. The device features a 2.5 MHz unity gain bandwidth, 6 V/μs slew rate, and is internally unity-gain compensated. Inputs are protected against reverse polarity (input voltage less than V–) and ESD (electrostatic discharge). Output is current-limited for both sourcing and sinking. Output short-circuits of unlimited duration are allowed, provided the power dissipation specification is not exceeded. The MIC6211 is available in the tiny, 5-lead SOT-23-5 surface-mount package.

4.0 APPLICATION INFORMATION

4.1 Common-Mode Range and Output

The input common-mode range of the MIC6211 is from the negative supply voltage to 1.2V below the positive supply voltage. The output voltage swings within 1V of the positive and negative supply voltage.

4.2 Voltage Buffer

Figure 4-1 shows a standard voltage follower/buffer. The output voltage equals the input voltage. This circuit is used to buf fer a high impedance signal source. This circuit works equally well with single or split supplies. VIN VOUT = VIN VOUT FIGURE 4-1: Voltage Buffer.

4.3 Inverting Amplifier

Figure 4-2 shows an inverting amplifier with its gain set by the ratio of two resistors. This circuit works best with split supplies, but will perform with single supply systems if the non-inverting input (+ input) is biased up above ground. 4VIN VOUT VOUT = –VIN FIGURE 4-2: Inverting Amplifier.

4.4 Voltage Controlled Current Sink

Figure 4-3 is a voltage controlled current sink. A buffer transistor forces current through a programming resistor until the feedback loop is satisfied. Current flow is VIN/R. This circuit works with single or split supplies. VIN RI VIN R FIGURE 4-3: Voltage Controlled Current Sink.

4.5 High-Pass Filter

Figure 4-4 is an active filter with 20 dB (10×) gain and a low frequency cutoff of 10 Hz. The high gain-bandwidth of the MIC621 1 allows operation beyond 100 kHz. This filter configuration is designed for split supplies. 1μF 1μF 332k 0.1μF 7.5k VIN VOUT FIGURE 4-4: High–Pass Filter.

4.6 Summing Amplifier

Figure 4-5 is a single supply summing amplifier . In this configuration, the output voltage is the sum of V1 and V2, minus the sum of V3 and V4. By adding more resistors to either the inverting or non-inverting input, more voltages may be summed. This single supply version has one important restriction: the sum of V1 and V2 must exceed the sum of V3 and V4, since the output voltage cannot pull below zero with only a single supply. VOUT R R R R R R All resistors are equal. VOUT = V1 + V2 – V3 – V4 V1 + V2 > V3 + V4 for single supply operation FIGURE 4-6: Summing Amplifier.

ISBN: 978-1-5224-6417-4 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 i n 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.
