• Manufacturer Part Number: MCP6281
• Description: 450 uA, 5 MHz Rail-to-Rail Op Amp
• Manufacturer: Microchip Technology

MCP6281/2/3/4/5
3.0
Descriptions of the pins are listed in Table 3-1 (single op amps) and Table 3-2 (dual and quad op amps).
TABLE 3-1:
TABLE 3-2:
3.1
The output pins are low-impedance voltage sources.
3.2
The non-inverting and inverting inputs are high-
impedance CMOS inputs with low bias currents.
3.3
For the MCP6285 only, the output of op amp A is
connected directly to the non-inverting input of
op amp B; this is the V
makes it possible to provide a Chip Select pin for duals
in 8-pin packages.

This is a CMOS, Schmitt-triggered input that places the
part into a low-power mode of operation.

Typically, these parts are used in a single (positive)
supply configuration. In this case, V
ground and V
need a local bypass capacitor (typically 0.01 µF to
0.1 µF) within 2 mm of the V
to use a bulk capacitor (within 100 mm), which can be
shared with nearby analog parts.
