MCP6471/2/4

2 MHz, Low-Input Bias Current Op Amps

Features

Description

• Low-Input Bias Current

- 150 pA (typical, T_A= +125°C)

• Low Quiescent Current

- 100 µA/amplifier (typical)

• Low-Input Offset Voltage

- ±1.5 mV (maximum)

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.

• Supply Voltage Range: 2.0V to 5.5V

• Rail-to-Rail Input/Output

• Gain Bandwidth Product: 2 MHz (typical)

• Slew Rate: 1.1 V/µs (typical)

• Unity Gain Stable

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.

• No Phase Reversal

• Small Packages

- Singles in SC70-5, SOT-23-5

• Extended Temperature Range

- -40°C to +125°C
