Description
The MCP6291 (single), MCP6292 (dual), and MCP6294 (quad) devices comprise a family of general-purpose, low-power operational amplifiers. Features such as rail-to-rail input and output swings, low quiescent current (600-µA/ch typical) combined with a wide bandwidth of 10 MHz, and low noise (8.7 nV/√Hz at 10 kHz) make this family attractive for a variety of applications that require a balance between cost and performance. The low input bias current enables the family to be used in applications with high-source impedances.
The robust design of the MCP629x provides ease-of-use to the circuit designer: a unity-gain stable, integrated RFI and EMI rejection filter, no phase reversal in overdrive condition, and high electrostatic discharge (ESD) protection (4-kV HBM).
The MCP629x family operates over the extended temperature range of –40°C to 125°C. The family has a power supply range of 2.4 V to 5.5 V.
