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.
