MCP6041/2/3/4
600 nA, Rail-to-Rail Input/Output Op Amps
Features
Description
• Low Quiescent Current: 600 nA/amplifier (typical)
• Rail-to-Rail Input/Output
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.
• Gain Bandwidth Product: 14 kHz (typical)
• Wide Supply Voltage Range: 1.4V to 6.0V
• Unity Gain Stable
• Available in Single, Dual, and Quad
• Chip Select (CS) with MCP6043
• Available in 5-lead and 6-lead SOT-23 Packages
• Temperature Ranges:
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.
- Industrial: -40°C to +85°C
- Extended: -40°C to +125°C
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.
