Description
The Microchip Technology Inc. MCP6V71/1U/2/4
family of operational amplifiers provides input offset
voltage correction for very low offset and offset drift.
These are low-power devices with a gain bandwidth
product of 2 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 2V, while drawing
170 µA/amplifier (typical) of quiescent current.
The MCP6V71/1U/2/4 family has enhanced EMI pro-
tection 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 Microchip Technology Inc. MCP6V71/1U/2/4 op
amps are offered in single (MCP6V71 and
MCP6V71U), dual (MCP6V72) and quad (MCP6V74)
packages. They were designed using an advanced
CMOS process.
