- Extended: -40°C to +125°C
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 (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 MCP6141/2/3/4 amplifiers have a gain bandwidth
product of 100 kHz (typical) 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.
