Description

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 A (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 V_DD + 300mV to V_SS 300 mV. This family of operational amplifiers is designed with Microchip's advanced CMOS process.

The MCP6271 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 CSinput puts the device in Low-power mode.

The MCP6271/2/3/4/5 family operates over the Extended Temperature Range of -40°C to +125°C, with a power supply range of 2.0V to 5.5V.
