Description
The Microchip Technology Incorporated
MCP6V81/1U/2/4 family of operational amplifiers
provides input offset voltage correction for very low
offset and offset drift. These devices have a gain
bandwidth product of 5 MHz (typical). They are
unity-gain stable, have virtually no 1/f noise and have
good Power Supply Rejection Ratio (PSRR) and
Common Mode Rejection Ratio (CMRR). These
products operate with a single supply voltage as low as
2.2V, while drawing 500 µA/amplifier (typical) of
quiescent current.
The MCP6V81/1U/2/4 family has enhanced EMI
protection to minimize any electromagnetic
interference from external sources. This feature makes
it well suited for EMI-sensitive applications such as
power lines, radio stations and mobile
communications, etc.
The MCP6V81/1U/2/4 op amps are offered in single
(MCP6V81 and MCP6V81U), dual (MCP6V82) and
quad (MCP6V84) packages. They were designed
using an advanced CMOS process.
