MCP6044-I/SL

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.

Comparable quad rail‑to‑rail CMOS op‑amps include Microchip MCP6004, Texas Instruments LMC6484, and Analog Devices AD8544. Verify supply range, input/output swing, bandwidth, offset, pinout and temperature range against MCP6044‑I/SL before substituting.

MCP6044-I/SL features:
- Quad rail-to-rail input/output operational amplifiers in one package
- Industrial temperature range: -40°C to +125°C
- Single-supply operation with input common-mode range and outputs that swing to the rails (light load)
- Unity-gain stable; suitable for buffers and various amplifier configurations
- Low power quiescent current per amplifier for long battery life
- Very low input bias current and low input offset voltage (typical Microchip RRIO op-amps)
- 14-pin package; RoHS-compliant lead-free (I/SL denotes industrial temp version in this package)
- Ideal for sensor conditioning, buffering, amplification in compact, low-power, rugged applications

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.
