OPA4316IDR Equivalent & Substitute Parts

Part Overview

The OPA4316IDR is a CMOS rail-to-rail operational amplifier manufactured by Texas Instruments, configured as a 4-circuit integrated circuit in 14-SOIC surface mount packaging. This device is classified as Active product status and is designed for general-purpose amplification applications requiring low input bias current and rail-to-rail output capability.

Substitute parts are identified when design requirements permit relaxation of specific electrical parameters while maintaining functional compatibility within the same package footprint and pin configuration. The OPA4316IDR operates across a 1.8V to 5.5V supply range with a 10 MHz gain-bandwidth product and 6V/µs slew rate, establishing the baseline performance envelope for equivalent device selection.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following mandatory criteria:

Package Compatibility: All substitute parts must use 14-SOIC surface mount packaging with identical 0.154" (3.90mm) width to ensure PCB footprint compatibility and automated assembly process alignment.

Circuit Configuration: All substitute parts must provide 4 independent operational amplifier circuits within a single package to maintain pin-for-pin compatibility.

Output Architecture: All substitute parts must feature rail-to-rail output capability to preserve signal swing characteristics across the supply voltage range.

Supply Voltage Range: Substitute parts must support the minimum 1.8V supply requirement of the OPA4316IDR. Maximum supply voltage may equal or exceed 5.5V.

Operating Temperature Range: Substitute parts must support the full -40°C to 125°C operating temperature envelope or a subset thereof that includes this range.

Electrical Performance Relaxation: The following parameters may be relaxed in substitute parts while maintaining functional equivalence:

• Slew Rate: May be lower than 6V/µs
• Gain Bandwidth Product: May be lower than 10 MHz
• Input Bias Current: May be higher than 5 pA
• Input Offset Voltage: May be higher than 500 µV
• Supply Current: May be higher than 400 µA
• Output Current per Channel: May be lower than 50 mA

Compliance Requirements: All substitute parts must maintain ROHS3 compliance and EAR99 export classification.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

MCP6294-E/SL and MCP6294T-E/SL are the closest functional equivalents to the OPA4316IDR. Both devices match the 10 MHz gain-bandwidth product and exceed the 6V/µs slew rate specification. These parts maintain ROHS3 compliance, feature MSL 1 moisture sensitivity rating, and support the full -40°C to 125°C operating temperature range. The primary distinction between these two is packaging format: MCP6294-E/SL is supplied in Tube packaging, while MCP6294T-E/SL is supplied in Cut Tape format. Both support supply voltages up to 6V, exceeding the OPA4316IDR maximum of 5.5V.

Secondary Substitutes (Reduced Performance):

LMV824IDT and LMV824IYDT are functionally equivalent STMicroelectronics devices with identical electrical specifications. Both support the full -40°C to 125°C temperature range and feature MSL 1 rating. These parts are qualified to AEC-Q100 automotive standards. The slew rate (1.9V/µs) and gain-bandwidth product (5.5 MHz) are reduced compared to the OPA4316IDR, but output current per channel is increased to 70 mA. Minimum supply voltage is 2.5V, which exceeds the OPA4316IDR requirement of 1.8V.

Conditional Substitutes (Temperature or Performance Limitations):

LMV824DR2G (onsemi) operates only to 85°C maximum, which does not satisfy the full -40°C to 125°C requirement of the OPA4316IDR. This device is suitable only for applications with reduced temperature range requirements.

MCP6284-E/SL provides the lowest gain-bandwidth product (5 MHz) and lowest output current per channel (25 mA) among all substitutes. This device is suitable only for applications with relaxed bandwidth and output current requirements.

Compliance and Certification:

All substitute parts maintain ROHS3 compliance and EAR99 export classification, matching the OPA4316IDR regulatory status. LMV824IDT and LMV824IYDT carry AEC-Q100 automotive qualification, which is not specified for the OPA4316IDR.

Frequently Asked Questions (FAQ)

Q: Can LMV824DR2G replace OPA4316IDR in all applications?

A: No. LMV824DR2G operates only to 85°C maximum temperature, while OPA4316IDR is specified to 125°C. Substitution is valid only for applications with maximum operating temperature of 85°C or lower.

Q: What is the primary difference between MCP6294-E/SL and MCP6294T-E/SL?

A: Both devices have identical electrical specifications and performance characteristics. The difference is packaging format: MCP6294-E/SL is supplied in Tube packaging, while MCP6294T-E/SL is supplied in Cut Tape with Digi-Reel format. Selection depends on assembly process requirements and tape reel compatibility.

Q: Why do some substitute parts have higher input bias current than OPA4316IDR?

A: Input bias current is a relaxed parameter in substitute selection. LMV824 series devices (60-119 nA) have higher input bias current than OPA4316IDR (5 pA), but this relaxation is acceptable when the application does not require ultra-low bias current performance. MCP6284 and MCP6294 series maintain the 1 pA specification.

Q: Are all substitute parts pin-compatible with OPA4316IDR?

A: Yes. All substitute parts use 14-SOIC surface mount packaging with identical pinout and footprint. PCB layout modifications are not required for mechanical or electrical connection purposes.

Q: Which substitute part has the lowest supply current consumption?

A: LMV824IDT and LMV824IYDT both specify 300 µA total supply current (x4 channels), which is lower than OPA4316IDR at 400 µA. MCP6284-E/SL specifies 450 µA, while LMV824DR2G and MCP6294 series specify 1000 µA.

Q: Can MCP6284-E/SL be used in high-speed signal conditioning applications?

A: MCP6284-E/SL has a 5 MHz gain-bandwidth product and 2.5V/µs slew rate, both lower than OPA4316IDR. This device is suitable only for applications with bandwidth requirements below 5 MHz and slew rate requirements below 2.5V/µs.

Q: What is the significance of MSL rating differences between substitute parts?

A: Moisture Sensitivity Level (MSL) indicates the maximum time a component can be exposed to ambient conditions before soldering. OPA4316IDR has MSL 2 (1 Year), while most substitutes have MSL 1 (Unlimited). MSL 1 provides greater flexibility in storage and handling. LMV824DR2G has MSL 3 (168 Hours), which is more restrictive than OPA4316IDR.

Q: Do all substitute parts support the 1.8V minimum supply voltage of OPA4316IDR?

A: No. LMV824DR2G requires minimum 2.7V, LMV824IDT and LMV824IYDT require 2.5V, MCP6284-E/SL requires 2.2V, and MCP6294 series require 2.4V. Only MCP6284-E/SL approaches the 1.8V minimum specification. Applications requiring 1.8V operation must use OPA4316IDR or verify substitute part operation at the specific supply voltage.

Q: What is the maximum output current per channel for each substitute?

A: OPA4316IDR: 50 mA; LMV824DR2G: 45 mA; LMV824IDT and LMV824IYDT: 70 mA; MCP6284-E/SL, MCP6294-E/SL, and MCP6294T-E/SL: 25 mA each. Applications requiring output current above 25 mA must use LMV824 series or OPA4316IDR.
