- Extended: -40°C to +125°C
Description
The MCP6041/2/3/4 family of operational amplifiers
(op amps) from Microchip Technology Inc. operate with
a single supply voltage as low as 1.4V, while drawing
less than 1 µA (maximum) of quiescent current per
amplifier. These devices are also designed to support
rail-to-rail input and output operation. This combination
of features supports battery-powered and portable
applications.
The MCP6041/2/3/4 amplifiers have a gain-bandwidth
product of 14 kHz (typical) and are unity gain stable.
These specifications make these op amps appropriate
for low frequency applications, such as battery current
monitoring and sensor conditioning.
The MCP6041/2/3/4 family operational amplifiers are
offered in single (MCP6041), single with Chip Select
(CS) (MCP6043), dual (MCP6042), and quad
(MCP6044) configurations. The MCP6041 device is
available in the 5-lead SOT-23 package, and the
MCP6043 device is available in the 6-lead SOT-23
package.
