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