MCP6041/2/3/4
600 nA, Rail-to-Rail Input/Output Op Amps
Features Description
Low Quiescent Current: 600 nA/amplifier (typical) The MCP6041/2/3/4 family of operational amplifiers
(op amps) from Microchip Technology Inc. operate with
Rail-to-Rail Input/Output
a single supply voltage as low as 1.4V, while drawing
Gain Bandwidth Product: 14 kHz (typical)
less than 1 A (maximum) of quiescent current per
Wide Supply Voltage Range: 1.4V to 6.0V
amplifier. These devices are also designed to support
Unity Gain Stable
rail-to-rail input and output operation. This combination
Available in Single, Dual, and Quad
of features supports battery-powered and portable
Chip Select (CS) with MCP6043 applications.
Available in 5-lead and 6-lead SOT-23 Packages
The MCP6041/2/3/4 amplifiers have a gain-bandwidth
product of 14 kHz (typical) and are unity gain stable.
Temperature Ranges:
These specifications make these op amps appropriate
- Industrial: -40C to +85C
for low frequency applications, such as battery current
- Extended: -40C to +125C
monitoring and sensor conditioning.
The MCP6041/2/3/4 family operational amplifiers are
Applications
offered in single (MCP6041), single with Chip Select

(CS) (MCP6043), dual (MCP6042), and quad
(MCP6044) configurations. The MCP6041 device is
Wearable Products
available in the 5-lead SOT-23 package, and the
Temperature Measurement
MCP6043 device is available in the 6-lead SOT-23
Battery Powered
package.
