Description
The Microchip MCP6471/2/4 family of operational
amplifiers (op amps) has low-input bias current
(150 pA, typical at 125°C) and rail-to-rail input and
output operation. This family is unity gain stable and
has a gain bandwidth product of 2 MHz (typical). These
devices operate with a single-supply voltage as low as
2.0V, while only drawing 100 µA/amplifier (typical) of
quiescent current. These features make the family of
op amps well suited for photodiode amplifier, pH
electrode amplifier, low leakage amplifier, and battery-
powered signal conditioning applications, etc.
The MCP6471/2/4 family is offered in single
(MCP6471), dual (MCP6472), quad (MCP6474)
packages. All devices are designed using an advanced
CMOS process and fully specified in extended
temperature range from -40°C to +125°C.
