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.
