MCP6141/2/3/4

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)

(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.
