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 very-low noise
(8.7 nV/√Hz at 10 kHz) 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 MCP629x 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 electrostatic
discharge (ESD) protection (4-kV HBM).
The MCP629x family operates over the Extended
Temperature Range of –40°C to +125°C. It also has
a power supply range of 2.4 V to 5.5 V.
