Description
The Microchip Technology Inc. MCP6281/1R/2/3/4/5
family of operational amplifiers (op amps) provide wide
bandwidth for the current. This family has a 5 MHz Gain
Bandwidth Product (GBWP) and a 65° phase margin.
This family also operates from a single supply voltage
as low as 2.2V, while drawing 450 µA (typical) quiescent
current. Additionally, the MCP6281/1R/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
– 300 mV.
This family of operational amplifiers is designed with
Microchip’s advanced CMOS process.
The MCP6285 has a Chip Select (CS) input for dual op
amps in an 8-pin package. This device is manufactured
by cascading the 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 MCP6281/1R/2/3/4/5 family operates over the
Extended Temperature Range of -40°C to +125°C. It
also has a power supply range of 2.2V to 6.0V.
