MCP6281/2/3/4/5
450 µA, 5 MHz Rail-to-Rail Op Amp
Features
Description
• Gain Bandwidth Product: 5 MHz (typ.)
• Supply Current: IQ = 450 µA (typ.)
• Supply Voltage: 2.2V to 5.5V
The Microchip Technology Inc. MCP6281/2/3/4/5
family of operational amplifiers (op amps) provide wide
bandwidth for the current. This family has a 5 MHz
Gain Bandwidth Product (GBWP) and a 65° phase
margin. This family also operates from a single supply
voltage as low as 2.2V, while drawing 450 µA (typ.)
quiescent current. Additionally, the MCP6281/2/3/4/5
supports rail-to-rail input and output swing, with a
common mode input voltage range of VDD + 300 mV to
• Rail-to-Rail Input/Output
• Extended Temperature Range: -40°C to +125°C
• Available in Single, Dual and Quad Packages
• Single with Chip Select (CS) (MCP6283)
• Dual with Chip Select (CS) (MCP6285)
VSS – 300 mV. This family of operational amplifiers is
designed with Microchip’s advanced CMOS process.
Applications
The MCP6285 has a Chip Select (CS) input for dual op
amps in an 8-pin package. This device is manufactured
by cascading the two op amps (the output of op amp A
connected to the non-inverting input of op amp B). The
CS input puts the device in Low-power mode.
