Description
The MCP6141/2/3/4 family of non-unity gain stable
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 (max.) of
quiescent current per amplifier. These devices are also
designed to support rail-to-rail input and output swing.
The MCP6141/2/3/4 op amps have a gain bandwidth
product of 100 kHz (typ.) and are stable for gains of
10 V/V or higher. This specification makes these
devices appropriate for battery-powered applications
where higher frequency responses from the amplifier
are required.
The MCP6141/2/3/4 family of op amps are offered in
single (MCP6141), single with a Chip Select (CS) fea-
ture (MCP6143), dual (MCP6142) and quad
(MCP6144) configurations.
