Description
The Microchip Technology Inc. MCP6281/2/3/4/5
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 (typ.)
quiescent current. Additionally, the MCP6281/2/3/4/5
supports rail-to-rail input and output swing, with a
common mode input voltage range of V_DD + 300 mV 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 MCP6281/2/3/4/5 family operates over the
Extended Temperature Range of -40°C to +125°C. It
also has a power supply range of 2.2V to 5.5V.
