3 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-ofuse
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.
