1 MIC62 MIC62 IttyBitty Operational Amplifier General Description The MIC62 IttyBitty op amp is a general-purpose, highperformance, single- or split-supply, operational amplifier in a space-saving, surface-mount package. The MIC62 operates from V to 2V, single or differential (split) supply. The input common-mode range includes ground. The device features a 2.5MHz unity gain bandwidth, 6V/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 MIC62 is available in the tiny, 5-lead SOT-2-5 surface-mount package.

6 MIC62 Applications Information Common-Mode ange and Output Voltage The input common-mode range of the MIC62 is from the negative supply voltage to.2v below the positive supply voltage. The output voltage swings within V of the positive and negative supply voltage. Voltage Buffer Figure 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. = Figure. Voltage Buffer 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. 2 = 2 Figure 2. Inverting Amplifer Voltage Controlled Current Sink Figure is a voltage controlled current sink. A buffer transistor forces current through a programming resistor until the feedback loop is satisfied. Current flow is /. This circuit works with single or split supplies. High-Pass Filter Figure is an active filter with 2dB ( ) gain and a lowfrequency cutoff of Hz. The high gain-bandwidth of the MIC62 allows operation beyond khz. This filter configuration is designed for split supplies. µf µf 7.5k.µF 2k Figure a. High-Pass Filter (db) k k FEQUENCY (Hz) Figure b. High-Pass Filter esponse Summing Amplifier Figure 5 is a single supply summing amplifier. In this configuration, the output voltage is the sum of V and V2, minus the sum of V and V. 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 V and V2 must exceed the sum of V and V, since the output voltage cannot pull below zero with only a single supply. V V2 V V All resistors are equal. = V + V2 V V V + V2 > V + V for single supply operation,,, Figure 5. Summing Amplifier I Figure. Voltage Controlled Current Sink MIC62 6 April 26
