4.9.3
The MCP6295 provides the flexibility of Low-power
mode for dual op amps in an 8-pin package. The
MCP6295 eliminates the added cost and space in
battery-powered applications by using two single op
amps with Chip Select lines or a 10-pin device with one
Chip Select line for both op amps. Since the two op
amps are internally cascaded, this device cannot be
used in circuits that require active or passive elements
between the two op amps. However, there are several
applications where this op amp configuration with
Chip Select line becomes suitable. The circuits below
show possible applications for this device.
4.9.3.1
With the cascaded op amp configuration, op amp B can
be used to isolate the load from op amp A. In applica-
tions where op amp A is driving capacitive or low
resistance loads in the feedback loop (such as an
integrator circuit or filter circuit), the op amp may not
have sufficient source current to drive the load. In this
case, op amp B can be used as a buffer.
