LMV820ILT Equivalent & Substitute Parts

Part Overview

The LMV820ILT is a general-purpose operational amplifier manufactured by STMicroelectronics, packaged in SOT-23-6 surface mount configuration. This rail-to-rail output amplifier operates across a 2.5 V to 5.5 V supply range and is designed for low-power applications requiring single-circuit amplification. The device maintains active product status with ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified based on matching functional classification, package type, electrical operating parameters, and supply voltage compatibility. Alternative devices are selected when the primary part is unavailable or when application-specific performance characteristics require evaluation against equivalent alternatives.

• Tape & Reel packaging format

All substitute parts listed meet the primary matching parameters and maintain compliance certifications equivalent to or exceeding the LMV820ILT specification. Electrical performance characteristics (slew rate, gain bandwidth product, input bias current, output current capability) vary among substitutes and must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

LMV820ILT (Primary Device)

The LMV820ILT maintains active product status with full ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). This device is recommended for new designs and applications where long-term availability and standard handling procedures are required. Current inventory of 29,200 units supports production volume requirements.

MCP6283T-E/CH (Preferred Substitute)

The MCP6283T-E/CH is an active product from Microchip Technology with ROHS3 compliance and MSL 1 rating. This substitute provides comparable gain bandwidth product (5 MHz versus 5.5 MHz) and improved slew rate (2.5 V/µs versus 1.9 V/µs). Supply voltage range extends to 6 V maximum, providing broader operating flexibility. Current inventory of 2,810 units supports medium-volume applications.

MAX4481AUT+T (Low-Power Substitute)

The MAX4481AUT+T is an active product from Analog Devices Inc./Maxim Integrated with ROHS3 compliance and MSL 1 rating. This substitute is selected for ultra-low-power applications, offering the lowest supply current (50 µA versus 300 µA) and minimal input offset voltage (1 mV). Trade-offs include significantly reduced slew rate (0.08 V/µs) and gain bandwidth product (140 kHz), limiting applicability to low-frequency signal conditioning. Current inventory of 4,139 units supports low-power design requirements.

ISL28148FHZ-T7A (Not Recommended for New Designs)

The ISL28148FHZ-T7A carries obsolete product status and MSL 2 rating (1-year moisture sensitivity), making it unsuitable for new design implementations. While electrical parameters are acceptable, the obsolete classification and restricted moisture handling requirements present supply chain and manufacturing process risks. Current inventory of 1,133 units is limited. This device is listed for reference only in legacy system maintenance scenarios.

Frequently Asked Questions (FAQ)

Q: Can the MCP6283T-E/CH directly replace the LMV820ILT in existing designs?

A: The MCP6283T-E/CH is pin-compatible within the SOT-23-6 package and meets all primary substitution criteria. However, electrical performance differences exist. The MCP6283T-E/CH provides higher slew rate (2.5 V/µs versus 1.9 V/µs) and extended maximum supply voltage (6 V versus 5.5 V). Input offset voltage is lower (3 mV versus 3.5 mV). Supply current is higher (450 µA versus 300 µA). Circuit validation is required to confirm performance compatibility with specific application requirements.

Q: What is the significance of the ISL28148FHZ-T7A obsolete status?

A: Obsolete product status indicates the manufacturer has discontinued production and support. The ISL28148FHZ-T7A carries MSL 2 rating, requiring controlled moisture exposure (1-year shelf life with desiccant packaging). New designs should not incorporate obsolete devices. Existing systems using this part may face supply constraints and extended lead times.

Q: How do supply current differences affect device selection?

A: Supply current ranges from 50 µA (MAX4481AUT+T) to 900 µA (ISL28148FHZ-T7A). The LMV820ILT operates at 300 µA. For battery-powered or energy-constrained applications, the MAX4481AUT+T reduces power consumption by 83%. For applications requiring higher output current capability and faster signal response, the ISL28148FHZ-T7A or MCP6283T-E/CH provide enhanced performance at the cost of increased supply current.

Q: Are all substitute parts available in Tape & Reel packaging?

A: All listed substitute parts are supplied in Tape & Reel (TR) packaging format, matching the LMV820ILT packaging specification. This format is standard for automated assembly processes and high-volume production environments.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts maintain ROHS3 compliance and REACH Unaffected status, matching the LMV820ILT regulatory classification. The LMV820ILT, MAX4481AUT+T, and MCP6283T-E/CH carry MSL 1 (unlimited moisture sensitivity). The ISL28148FHZ-T7A carries MSL 2 (1-year moisture sensitivity), requiring enhanced handling procedures.

Q: Can the MAX4481AUT+T be used in high-frequency applications?

A: The MAX4481AUT+T is not suitable for high-frequency applications. The gain bandwidth product of 140 kHz and slew rate of 0.08 V/µs limit this device to low-frequency signal conditioning, precision measurement, and ultra-low-power applications. For applications requiring bandwidth above 1 MHz, the LMV820ILT, MCP6283T-E/CH, or ISL28148FHZ-T7A are appropriate selections.

Q: What output current capability differences exist among substitutes?

A: Output current per channel ranges from 17 mA (MAX4481AUT+T) to 75 mA (ISL28148FHZ-T7A). The LMV820ILT provides 70 mA output current. Applications requiring high-current output buffering should select the ISL28148FHZ-T7A or LMV820ILT. Low-power applications with minimal load current can utilize the MAX4481AUT+T.
