概要
Description
MCP6044-I/SL is Microchip’s quad operational amplifier optimized for ultra-low power, single-supply operation. The “I” denotes industrial temperature range (-40°C to +125°C) and “/SL” indicates the SOIC/SL packaging. It contains four identical rail-to-rail input/output op-amps in one 14-pin package. It typically runs from a single supply of about 1.8 to 5.5 V, with low quiescent current, low input bias/offset, and unity-gain stability. The device is ideal for battery-powered sensor conditioning, data-acquisition front ends, buffering, active filtering, and general signal conditioning in rugged environments. Each amplifier is independent but shares the same supply, and no external compensation is required. For detailed electrical specs, pinout, and performance curves, refer to the datasheet.

Pinout
The MCP6044‑I/SL is a 14‑pin quad operational amplifier. Function: it contains four independent op‑amps (rail‑to‑rail input/output, single‑supply operation). Pin breakdown (total 14 pins): 4 outputs, 4 non‑inverting (+) inputs, 4 inverting (−) inputs, VDD (positive supply) and VSS (negative/ground). In short: 4 op amps × (IN+, IN−, OUT) = 12 signal pins + 2 power pins = 14 pins.
