    4.4 ВµA/Amplifier, 90 kHz Op Amp
    Features: Description: Low Quiescent Current:
    -4.4 ВµA/amplifier (typical) Low Input Offset Voltage:
    -В±1.0 mV (maximum) Enhanced EMI Protection:
    -Electromagnetic Interference Rejection Ratio
    (EMIRR) at 1.8 GHz: 97 dB Supply Voltage Range: 1.8V to 5.5V Gain Bandwidth Product: 90 kHz (typical) Rail-to-Rail Input/Output Slew Rate: 0.05 V/Вµs (typical) Unity Gain Stable No Phase Reversal Small Packages:
    -Singles in SC70-5, SOT-23-5
    -Dual in MSOP-8, SOIC-8
    -Quad in SOIC-14, TSSOP-14 The Microchip Technology Inc. MCP6421/2/4 family of
    operational amplifiers operate with a single supply
    voltage as low as 1.8V, while drawing low quiescent
    current per amplifier (5.5 ВµA, maximum). This family
    also has low-input offset voltage (В±1.0 mV, maximum)
    and rail-to-rail input and output operation. In addition,
    the MCP6421/2/4 family is unity gain stable and has a
    gain bandwidth product of 90 kHz (typical). This
    combination of features supports battery-powered and
    portable applications. The MCP6421/2/4 family has
    enhanced EMI protection to minimize any
    electromagnetic interference from external sources.
    This feature makes it well suited for EMI sensitive
    applications such as power lines, radio stations, and ...
