MCP6481/2/4  
4 MHz, Low-Input Bias Current Op Amps  
Features  
Description  
• Low-Input Bias Current  
- 150 pA (typical, TA = +125°C)  
• Low Quiescent Current  
- 240 µA/amplifier (typical)  
• Low-Input Offset Voltage  
- ±1.5 mV (maximum)  
The Microchip MCP6481/2/4 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 4 MHz (typical). These  
devices operate with a single-supply voltage as low as  
2.2V, while only drawing 240 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: 2.2V to 5.5V  
• Rail-to-Rail Input/Output  
• Gain Bandwidth Product: 4 MHz (typical)  
• Slew Rate: 2.7 V/µs (typical)  
• Unity Gain Stable  
The MCP6481/2/4 family is offered in single  
(MCP6481), dual (MCP6482), quad (MCP6484)  
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
