Rail-to-rail op amp for applications requiring a good balance between cost and performance
The MCP6291 (single), MCP6292 (dual), and MCP6294 (quad) devices, from Texas Instruments, comprise a family of general-purpose, low-power operational amplifiers. Features such as rail-to-rail input and output swings, low quiescent current (600µA/ch typical) combined with a wide bandwidth of 10MHz, and very-low noise (8.7nV/vHz at 10kHz) make this family attractive for a variety of applications that require a good balance between cost and performance. Its low input bias current enables the family to be used in applications with high-source impedances.
The robust design of the devices provides ease-of-use to the circuit designer—a unity-gain stable, integrated RFI/EMI rejection filter, no phase reversal in overdrive condition, and high ESD protection (4kV HBM).
The family operates over the Extended Temperature Range of –40C to +125C. It also has a power supply range of 2.4V to 5.5V.
