Description:
The MCP6141/2/3/4 family of non-unity gain stable
operational amplifiers (op amps) from Microchip Tech-
nology Inc. operate with a single supply voltage as low
as 1.4V, while drawing less than 1
μA
(max.) of quies-
cent current per amplifier. These devices are also
designed to support rail-to-rail input and output opera-
tion. This combination of features supports
battery-powered and portable applications.
The MCP6141/2/3/4 amplifiers have a gain bandwidth
product of 100 kHz (typ.) and are stable for gains of
10 V/V or higher. These specifications make these op
amps appropriate for battery powered applications
where a higher frequency response from the amplifier
is required.
The MCP6141/2/3/4 family operational amplifiers are
offered in single (MCP6141), single with Chip Select
(CS) (MCP6143), dual (MCP6142) and quad
(MCP6144) configurations. The MCP6141 device is
available in the 5-lead SOT-23 package, and the
MCP6143 device is available in the 6-lead SOT-23
package.
