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
+ 0.3V (max.)
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),
(MCP6144) configurations.

    ... A 5V difference would cause current to flow, which is greater than the input current of the MCP6141/2/3/4 family at 25°C (1 pA, typ). The simplest technique to reduce surface leakage is using a guard ring around sensitive pins (or traces). The guard ring is biased at the same voltage as the sensitive pin or trace ...

    ... SIGNAL COUPLING The input pins of the MCP6141/2/3/4 family of op amps are high impedance, which allows noise injection. This noise can be capacitively or magnetically coupled. In either case, using a ground plane helps reduce noise injection. When noise is coupled capacitively, the ground plane provides shunt capacitance to ground for high fre- quency signals (Figure 3-8 shows the equivalent cir- cuit) ...
