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.
