MCP6421/2/4 4.4 A/Amplifier, 90 kHz Op Amp Features: Description: The Microchip Technology Inc. MCP6421/2/4 family of Low Quiescent Current: operational amplifiers operate with a single supply - 4.4 A/amplifier (typical) voltage as low as 1.8V, while drawing low quiescent Low Input Offset Voltage: current per amplifier (5.5 A, maximum). This family - 1.0 mV (maximum) also has low-input offset voltage (1.0 mV, maximum) Enhanced EMI Protection: and rail-to-rail input and output operation. In addition, the MCP6421/2/4 family is unity gain stable and has a - Electromagnetic Interference Rejection Ratio gain bandwidth product of 90 kHz (typical). This (EMIRR) at 1.8 GHz: 97 dB combination of features supports battery-powered and Supply Voltage Range: 1.8V to 5.5V portable applications. The MCP6421/2/4 family has Gain Bandwidth Product: 90 kHz (typical) enhanced EMI protection to minimize any Rail-to-Rail Input/Output electromagnetic interference from external sources. Slew Rate: 0.05 V/s (typical) This feature makes it well suited for EMI sensitive Unity Gain Stable applications such as power lines, radio stations, and mobile communications, etc. No Phase Reversal Small Packages: The MCP6421/2/4 family is offered in single (MCP6421), dual (MCP6422) and quad (MCP6424) - Singles in SC70-5, SOT-23-5 packages. All devices are designed using an advanced - Dual in MSOP-8, SOIC-8 CMOS process and fully specified in extended - Quad in SOIC-14, TSSOP-14 temperature range from -40C to +125C.
