Detailed Description

Single-channel CMOS operational amplifier for general-purpose analog signal conditioning. Industrial temperature grade. Rail-to-rail performance, low power, and unity-gain stability make it easy to drop into a wide range of designs. Package suffix “/SN” indicates 8‑lead SOIC (narrow body). Main Category: Integrated Circuits (ICs). Small Classification: Specialized ICs.

Key Features

Single op amp, unity-gain stable

Rail-to-rail input and output (RRIO) for maximum signal swing on low supplies

Low quiescent current for battery-powered designs

Wide supply range (typical low-voltage operation; consult datasheet for exact limits)

Low input bias current and low offset (precision CMOS input stage)

ESD-protected device with robust operating margins

Industrial temperature range

Multiple package options in same family for layout flexibility

Key Advantages

Simple to design-in; behaves predictably across gain settings

Works well on 3V and 5V rails, reducing BOM complexity

Saves power while maintaining strong analog performance

RRIO maximizes dynamic range with low supply voltages

Stable across temperature; suitable for industrial environments

Backed by Microchip’s long-life support and Y-IC’s reliable sourcing

Packaging

Type: 8‑Lead SOIC (Narrow), Microchip code “SN”

Material: Molded epoxy, Pb‑free, RoHS compliant; matte‑tin plated leads

Approximate Size: body ~4.9 mm × 3.9 mm; height ~1.5 mm; lead pitch 1.27 mm

Pin Configuration (typical single op amp): V+ (supply), V−/GND (supply), IN+, IN−, OUT; remaining pins are no connects (orientation via notch/mark)

Tape & Reel and Tube options available (check orderable suffixes on datasheet)

Thermal Characteristics: typical SOIC‑8 thermal resistance values; actual θJA/θJC depend on PCB and airflow (see datasheet for measured data)

Electrical Properties (at a glance): CMOS input, RRIO behavior, unity‑gain stability, low power operation; supply voltage range and detailed limits per datasheet

Note: “Package / Case: 590” is a vendor code; functional package is SOIC‑8 (SN)

Lifecycle

Status: Active and supported by Microchip at the time of publication

Not nearing discontinuation based on current information

Equivalent or Alternative Models (verify pinout/specs before substitution):

- Microchip MCP601‑I/SN (single, RRIO, lower bandwidth/power)

- Microchip MCP6001‑I/SN (single, ultra‑low‑power RRIO)

- Microchip MCP6021‑I/SN (single, RRIO, different bandwidth/noise profile)

- Package variants of the same device family: MCP603‑I/P (PDIP‑8), MCP603‑I/SL (MSOP‑8)

- Cross‑vendor examples (design review required): TI TLV9061, OPA316 (RRIO single op amps)
