Design Aids
The Microchip Technology Inc. MCP6281/1R/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 (typical) quiescent current. Additionally, the MCP6281/1R/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.
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.
The MCP6281/1R/2/3/4/5 family operates over the Extended Temperature Range of -40°C to +125°C. It also has a power supply range of 2.2V to 6.0V.
