What the 45 µA supply current per channel buys you
The MCP6404-E/SL draws 45 µA per channel. The 1 MHz gain-bandwidth product and 0.5 V/µs slew rate suit DC offset correction and low-frequency filtering. Rail-to-rail output swing drives an ADC input without a second supply rail.
Input bias current and offset — the CMOS advantage
With 1 pA typical input bias current and 800 µV maximum input offset voltage, the MCP6404 interfaces directly with high-impedance sources without a separate buffer stage.
Lifecycle and sourcing reality
The Tube shipping medium is standard for engineering samples and small-batch production.
