MCP6471/2/4
2 MHz, Low-Input Bias Current Op Amps
Features Description
Low-Input Bias Current The Microchip MCP6471/2/4 family of operational
amplifiers (op amps) has low-input bias current
- 150 pA (typical, T = +125C)
A
(150 pA, typical at 125C) and rail-to-rail input and
Low Quiescent Current
output operation. This family is unity gain stable and
- 100 A/amplifier (typical)
has a gain bandwidth product of 2 MHz (typical). These
Low-Input Offset Voltage
devices operate with a single-supply voltage as low as
- 1.5 mV (maximum)
2.0V, while only drawing 100 A/amplifier (typical) of
Supply Voltage Range: 2.0V to 5.5V quiescent current. These features make the family of
op amps well suited for photodiode amplifier, pH
Rail-to-Rail Input/Output
electrode amplifier, low leakage amplifier, and battery-
Gain Bandwidth Product: 2 MHz (typical)
powered signal conditioning applications, etc.
Slew Rate: 1.1 V/s (typical)
The MCP6471/2/4 family is offered in single
Unity Gain Stable
(MCP6471), dual (MCP6472), quad (MCP6474)
