| MIC6211 Micrel, Inc. MIC6211 IttyBittyTM Operational Amplifier General Description The MIC6211 IttyBittyTM op amp is a general-purpose, highperformance, single- or split-supply, operational amplifier in a space-saving, surface-mount package. The MIC6211 operates from 4V to 32V, single or differential (split) supply. The input common-mode range includes ground. The device features a 2.5MHz unity gain bandwidth, 6V/s 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.

High-Pass Filter Figure 4 is an active filter with 20dB (10x) gain and a lowfrequency cutoff of 10Hz. The high gain-bandwidth of the MIC6211 allows operation beyond 100kHz. This filter configuration is designed for split supplies. 0.1F 332k 1F 1F Applications Information Common-Mode Range and Output Voltage 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. Voltage Buffer Figure 1 shows a standard voltage follower/buffer. The output voltage equals the input voltage. This circuit is used to buffer a high impedance signal source. This circuit works equally well with single or split supplies. VIN 3 1 4 VIN 7.5k 4 1 3 VOU T VOU T Figure 4a. High-Pass Filter 30 VOUT= VIN VOUT (dB) 20 10 0 Inverting Amplifier Figure 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. R1 VIN Figure 4b. High-Pass Filter Response Summing Amplifier Figure 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.

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.
