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
