MCP6491/2/4 7.5 MHz, Low-Input Bias Current Op Amps Features Description Low-Input Bias Current The Microchip MCP6491/2/4 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 - 530 A/amplifier (typical) has a gain bandwidth product of 7.5 MHz (typical). Low-Input Offset Voltage These devices operate with a single-supply voltage as - 1.5 mV (maximum) low as 2.4V, while only drawing 530A/amplifier Supply Voltage Range: 2.4V to 5.5V (typical) of quiescent current. These features make the family of op amps well suited for photodiode amplifier, Rail-to-Rail Input/Output pH electrode amplifier, low leakage amplifier, and Gain Bandwidth Product: 7.5 MHz (typical) battery-powered signal conditioning applications, etc. Slew Rate: 6 V/s (typical) The MCP6491/2/4 family is offered in single Unity Gain Stable (MCP6491), dual (MCP6492), quad (MCP6494) No Phase Reversal packages. All devices are designed using an advanced Small Packages CMOS process and fully specified in extended - Singles in SC70-5, SOT-23-5 temperature range from -40C to +125C.
