Description

The Microchip Technology Inc. MCP6284 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 A (typ.) quiescent current. Additionally, the MCP6284 supports rail-to-rail input and output swing, with a common mode input voltage range of VDD + 300 mV to V_SS 300 mV. This family of operational amplifiers is designed with Microchip's advanced CMOS process.

The MCP6284 has aChip 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 CSinput puts the device in Low-power mode.

The MCP6284 family operates over the Extended Temperature Range of -40 to +125. It also has a power supply range of 2.2V to 5.5V.
