MCP6271/2/3/4/5
170 µA, 2 MHz Rail-to-Rail Op Amp
Features
Description
• Gain Bandwidth Product: 2 MHz (typ.)
• Supply Current: IQ = 170 µA (typ.)
• Supply Voltage: 2.0V to 5.5V
The Microchip Technology Inc. MCP6271/2/3/4/5 family
of operational amplifiers (op amps) provide wide
bandwidth for the current. This family has a 2 MHz Gain
Bandwidth Product (GBWP) and a 65° phase margin.
This family also operates from a single supply voltage
as low as 2.0V, while drawing 170 µA (typ.) quiescent
current. Additionally, the MCP6271/2/3/4/5 supports
rail-to-rail input and output swing, with a common mode
input voltage range of VDD + 300 mV to VSS – 300 mV.
This family of operational amplifiers is designed with
Microchip’s advanced CMOS process.
• 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) (MCP6273)
• Dual with Chip Select (CS) (MCP6275)
Applications
The MCP6275 has a Chip Select input (CS) for dual op
amps in an 8-pin package and is manufactured by
cascading 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.
