Description
The Microchip Technology Inc. MCP6291/1R/2/3/4/5
family of operational amplifiers (op amps) provide wide
bandwidth for the current. This family has a 10 MHz
Gain Bandwidth Product (GBWP) and a 65° phase
margin. This family also operates from a single supply
voltage as low as 2.4V, while drawing 1 mA (typical)
quiescent current. In addition, the MCP6291/1R/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 MCP6295 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, with the output of
op amp A being connected to the noninverting input of
op amp B. The CS input puts the device in a Low-power
mode.
The MCP6291/1R/2/3/4/5 family operates over the
extended temperature range of -40°C to +125°C. The
MCP6292 H-Temp part is available in the 8-Lead
MSOP package and operates over the high
temperature range of -40°C to +150°C. It also has a
power supply range of 2.4V to 6.0V.
