MCP6476/6R/6U/7/9 3 MHz Operational Amplifier with EMI Filtering Features Description The Microchip Technology Inc. MCP6476/6R/6U/7/9 Low Quiescent Current: operational amplifier (op amp) operates with a single - 170 A (maximum)/amplifier supply voltage as low as 1.8V, while drawing low quies- Low Input Offset Voltage: cent current (170 A, maximum per amplifier). This op - 1.6 mV (maximum) amp also has low input offset voltage (1.6 mV, maxi- Enhanced EMI Protection: mum), and rail-to-rail input and output operation. In addition, the MCP6476/6R/6U/7/9 is unity gain stable - Electromagnetic Interference Rejection Ratio (EMIRR) at 1.8 GHz: 90 dB and has a gain bandwidth product of 3 MHz (typical). This combination of features supports battery-powered Supply Voltage Range: 1.8V to 5.5V and portable applications. Gain Bandwidth Product: 3 MHz (typical) The MCP6476/6R/6U/7/9 has enhanced EMI protec- Rail-to-Rail Input/Output tion minimizing Electromagnetic Interference from Unity Gain Stable external sources. This feature makes it well-suited for No Phase Reversal EMI-sensitive applications, such as power lines, radio Quick Start-up Time: 6 s (typical) stations and mobile communications. Small Packages This product family is offered in single (MCP6476), dual Extended Temperature Range: -40C to +125C (MCP6477) and quad (MCP6479) packages. All AEC Q100 Qualified, Grade 1 devices are designed using an advanced CMOS pro- cess and fully specified in the extended temperature Applications range, from -40C to +125C.
