Description
The Microchip Technology Inc. MCP6271/1R/2/3/4/5
family of operational amplifiers (op amps) provide wide
bandwidth for the current. This family has a 2 MHz
Gain Bandwidth Product (GBWP) and a 65° Phase
Margin. This family also operates from a single supply
voltage as low as 2.0V, while drawing 170 µA (typical)
quiescent current. The MCP6271/1R/2/3/4/5 supports
rail-to-rail input and output swing, with a common mode
input voltage range of V
DD
+300mV to V
SS
–300mV.
This family of op amps is designed with Microchip’s
advanced CMOS process.
The MCP6275 has a Chip Select input (CS
) for dual op
amps in an 8-pin package and is manufactured by
cascading two op amps (the output of op amp A
connected to the non-inverting input of op amp B). The
CS
input puts the device in low power mode.
The MCP6271/1R/2/3/4/5 family operates over the
Extended Temperature Range of –40°C to +125°C,
with a power supply range of 2.0V to 6.0V.
